Answer:
6
Explanation:
An egg cell has half the number of chromosomes which a somatic cell has. Thus, the egg cell of jimson weed will have 6 chromosomes.
Why does an egg cell have half the chromosomes?A set of chromosomes that an individual has is referred to as ploidy.
The somatic cells of an organism has two copies of chromosomes, such a cell is said to have its chromosome set as diploid (2N).
The diploid cells are formed by the fusion of two haploid cells (N), one comes from the mother and one from the father.
A zygote is formed by the fusion of the two gamete cells, an egg cell and a sperm.
Thus, since an egg cell is a gamete, its chromsome set is haploid. That is, it has half the number of chromosomes compared to a somatic cell.
Hence, as the somatic cells of the jimson weed Datura stramonium has 12 chromsomes,its egg cell will have half the number of chromsomes, which is 6 chromosomes.

Or how your muscles keep working when you're exercising so hard that they're very low on oxygen?
Both of these processes can happen thanks to alternative glucose breakdown pathways that occur when normal, oxygen-using (aerobic) cellular respiration is not possible—that is, when oxygen isn't around to act as an acceptor at the end of the electron transport chain. These fermentation pathways consist of glycolysis with some extra reactions tacked on at the end. In yeast, the extra reactions make alcohol, while in your muscles, they make lactic acid.
Fermentation is a widespread pathway, but it is not the only way to get energy from fuels anaerobically (in the absence of oxygen). Some living systems instead use an inorganic molecule other than \text {O}_2O

1. The poison leaf plant, also known as gifblaar (pictured above), contains fluoroacetic acid, a compound that interferes with the Krebs cycle, eventually causing it to shut down completely.
Which of these answer choices best describes the overall effects that would occur in an animal that consumes this plant?
Oxidative phosphorylation would not occur, the majority of ATP will not form, and the animal will not be able to survive.
2. On cool and brisk day, if you take a deep breath in and then exhale, you'll see a "fog" that forms as a result of your exhaled breath.
Which of the following products of cellular respiration does that "fog" contain?
Carbon dioxide and water
3. What is the correct pathway of anaerobic respiration in yeast?
Glycolysis ⇒ Alcohol Fermentation
Explanation:
1. Fluoroacetic Acid interferes with the Citric Acid Cycle (or Krebs Cycle) as it takes the place of Acetate, and is converted to fluorocitrate, which disrupts the whole cycle as it inhibits aconitase (an enzyme in the Krebs Cycle) and prevents the conversion of citrate to isocitrate. Therefore, oxidative phosphorylation would not occur, and oxidation of nutrients to produce energy would be halted.
2. Cellular respiration consists of several metabolic reactions occuring in the cells in order to convert energy from nutrients into adenosine triphosphate (ATP), carbon dioxide and water. So, the "fog" that forms as a result of your exhaled breath contains water and carbon dioxide. When we breathe, we take in Oxygen, and our lungs exhale Carbon dioxide. Breath also contains moisture from the mouth and lungs, so every breath also has water in the form of water vapor. Therefore, when the weather is cold outside, this water vapor condenses into small droplets of water that can be seen and is what looks like "fog"
3. Fermentation is an anaerobic process (in the absence of oxygen) that breaks down glucose. Under anaerobic conditions, Yeast converts glucose to pyruvate acid through glycolysis. Then NADH donates its electrons to the pyruvate acid (an organic molecule), thus producing ethanol.

When does a population experience logistic growth?
A. When it has access to unlimited resources
B. When it reaches the carrying capacity
C. When natural predators are introduced to the population
D. When there's primary succession
When the population attains the condition called carrying capacity, it causes logistic growth in the population.
Answer: Option B
Explanation:
The rate of development of population in an environment depends based upon the number of individuals surviving in the environment. It develops in size gradually when there are just a couple of people whereas it develops quicker when there are more people.
When the population reaches the carrying capacity of the environment which is nothing but the maximum number of individual which the environment can hold, it causes logistic growth due to non availability of resource as it is exhausted by the surviving population.
option B. Logistic growth in a population occurs when growth slows and becomes steady as the population approaches the carrying capacity of its environment due to limitations in resources.
Explanation:A population experiences logistic growth when it reaches a point of stability due to limitations in available resources, also known as the carrying capacity. In other words, logistic growth occurs when a population's growth slows down and remains steady as it approaches the carrying capacity of its environment. Initially, growth is rapid, similar to exponential growth. However, as the population approaches the carrying capacity, the resources in the environment are not sufficient for all members of the population, leading to competition and a slowdown in population growth.
Option A does not lead to logistic growth, but rather to exponential growth, which is unrestricted. Option C introduces a factor that may limit population growth but is not the definition of logistic growth. Finally, option D does not necessarily lead to logistic growth as primary succession refers to the establishment of a biological community in an area with no life.

A) Lemur Catta( lemur)
B) Hypobates lar (gibbon) C) Gorilla gorilla (gorilla)
D) Macaca Mulatta (Rhesus Monkey)
C. ...........................
Answer:
C) Gorilla gorilla (gorilla)
Explanation:
At least 15% of our genome is more similar to gorillas than our closest "relatives," chimpanzees.
First, you need to understand a few things. Gorillas, chimpanzees and humans all have one ancestor in common. First, gorillas distinguished themselves and followed their own evolutionary path. Then humans and chimpanzees broke up. That's why the chimpanzee is considered the most human-like animal - and the gorilla the second.
The data showed that the separation of gorillas from our common ancestor took place about 10 million years ago - four million before the separation between humans and chimpanzees.

two replication forks form a _________________?
Answer:
Tow replication forks form a lagging and leading strand.
Explanation:
During the process of DNA replication, there forms a Y shaped junction called replication fork. At each replication origin, two replication forks are formed in opposite polarities.
At one replication fork, a discontinuous stand is formed called lagging strand, and at the other replication fork, there forms a continuous strand in 5' to 3' direction called leading strand.
Tow replication forks form a lagging and leading strand in DNA replication
What is Replication fork ?It is a point where DNA replication occurs, otherwise called as growth point. At each origin, two replication forks are formed in opposite polarities.
It is Y-shaped structure forms at the junction between the newly separated template strands and the duplex DNA that has not yet been duplicated.
During initiation step of DNA replication, one strand can be easily duplicated, while the other strand can not easily duplicated due to polarity problem.
Secondly DNA polymerase synthesizes the DNA strand in the 5′-3' direction only.
Thus, one strand is continuous or leading strand where as other strand is discontinuous or lagging strand, generating Okazaki fragments.

if earth did not rotate, how would air at the equator move?
there would be no movement
air would sink and move towards the poles
air would rise and move towards the poles
Thank you so much for using brainly :)
Answer: Air would rise and move towards the poles hope this helps you out :) Please let me know if you have any more questions
Answer: Option (3)
Explanation: If the rotation of the earth stops, then there will be a direct impact on the existing air circulation pattern.
If the earth stops rotating, then there will be no generation of the coriolis force. Coriolis force is the force that comes into the picture when the moving air masses gets deflected in both the hemisphere due to the rotation of the earth.
If there is no coriolis force, then there is no deflection of air mass. So the air mass would simply rise up, being less dense and migrate towards the poles without changing its path.
Thus, the correct answer is option (3).
What do you think? Are humans an invasive species? Refer to the definition of invasive species to support your answer. Invasive species: A species that is not native to an ecosystem and causes environmental and/or economical harm.
Answer:
Yes, the humans are invasive species.
Explanation:
The homeland of the modern day humans is Africa, thus they are native o the African continent. But the humans started to spread gradually, first in Eurasia, and later in Australia, North America, South America, and the Pacific islands, to a point now where they have reached pretty much every corner of the world. This is a textbook example of an invasive species that has entered into new ecosystems. Not just that the humans were entering into new ecosystems, but they also were changing the ecosystems, more often then not causing a lot of damage on them, leading to the destruction of lot of habitats and extinction of lot of species.
Whether humans can be classified as an invasive species depends on one's perspective. By definition, humans can't be invasive since they are native to Earth. However, considering the widespread impact humans have had on the global ecosystem, much like invasive species, some argue that humans have invasive tendencies.
Explanation:Humans can be considered an invasive species depending on the perspective. Firstly, let's understand what characterizes an invasive species. An invasive species is defined as a species that is not native to a particular ecosystem and may cause environmental or economical harm by altering the environmental balance. They typically spread dramatically, out-competing native species for resources, disrupting food webs, and often carrying diseases.
Humans have often been responsible for the introduction of invasive species into new ecosystems, often causing significant environmental damage. However, whether humans are classified as invasive themselves can be debated. From one perspective, humans have spread to every continent on earth and have a profound impact on the global ecosystem. They have been responsible for large scale habitat destruction, extinction of native species and environmental/vyingal harm.
However, if we adhere strictly to the definition of invasive species, humans evolved on earth and hence, cannot be labelled 'non-native'. Also, whether humans are harmful to the environment or not can be subjective and is often viewed in terms of a 'harmful' or 'beneficial' balance. Although it's clear that human activities negatively impact the environment, there are many instances of humans working to restore ecosystems and protect native species too.

What might cause birds in population a to immigrate to the island? How will the level of competition among birds in population b change if many birds from population a join population b?
Birds from population A might immigrate to the island for better resources, to escape threats, or to follow established populations.
Immigration can increase competition among birds in population B, shift resource use, and change predator-prey dynamics.
The specific effects of immigration depend on various factors.
Reasons for immigration:
Better resources: The island might offer more abundant food sources, nesting sites, or other resources than the birds' current habitat in population A. This could be due to factors like fewer predators, more suitable vegetation, or a milder climate.
Escape from threats: The birds in population A might be facing threats in their current habitat, such as habitat loss, competition from other species, or disease. The island could offer a safer haven from these threats.
Following established populations: If birds from population A have already successfully colonized the island, this could attract other birds from the same population to follow suit. This phenomenon is known as social attraction.
Changes in competition:
Increased competition: If many birds from population A immigrate to the island, they will compete with the birds in population B for resources such as food, nesting sites, and mates. This could lead to increased competition among birds in population B, potentially harming their survival and reproductive success.
Shift in resource use: The arrival of new birds from population A could also lead to a shift in how resources are used on the island. For example, if the new birds occupy a different ecological niche than the birds in population B, they might not compete directly for the same resources. However, they could still indirectly affect each other by, for example, consuming prey that the other population relies on.
Changes in predator-prey dynamics: The arrival of new birds could also affect the predator-prey dynamics on the island. For example, if the new birds are prey for a predator that also preys on birds in population B, this could increase the overall predation pressure on both populations.
The specific effects of immigration on competition will depend on a variety of factors, including the number of birds that immigrate, the similarity of the two bird populations, and the resources available on the island.
Overall, the immigration of birds from population A to the island is likely to have a significant impact on the level of competition among birds in population B. The exact nature of this impact will depend on the specific circumstances, but it is likely to be complex and multifaceted.

the struggle between organism for resources
The struggle among organisms for the same limited natural resources is called competition.
Competition is a fundamental ecological interaction where organisms of the same or different species strive to obtain the same or similar resources that are in limited supply, such as food, water, shelter, and living space. This competition can occur within a population (intraspecific competition) or between different species (interspecific competition).
The struggle to acquire these limited resources is a key driver of natural selection, as organisms that are better adapted to obtain the necessary resources will have a higher probability of survival and reproduction, passing on their advantageous traits to future generations.

what does digestion have to do with cellular respiration
Answer:
Digestion "cleans out" the digestive system keeping it free of dead cells. It is important because it serves as the "fuel" for cellular respiration. The glucose is used to produce the ATP our body needs to perform essential functions. ATP is like the "energy currency"/"money" that the living cells "run on". The digestive tract provides the nutrient molecules, through the process of digestion, while the respiratory tract provides oxygen. As such, the two systems work together to give your cells the ingredients they need to produce energy, which they use to communicate, build cellular products and grow.

The process by which a body of hot magma intrudes into a region of cold rock near Earth's surface is known as A. surface metamorphism. B. regional metamorphism. C. intrusive metamorphism. D. contact metamorphism.
Answer:
D. contact metamorphism
Explanation:
When there's a volcanic activity in certain area, very often it happens that there's magma that intrudes into the cold rock in the surrounding area. The intrusion of the hot magma into the cold rock layers causes big changes into the structure of the rocks. The high temperature and high pressure manage to influence the structure of the preexisting rocks, mostly on the places where the magma touches the cold rocks, leading to the formation of metamorphic rocks. This type of metamorphism is known as contact metamorphism.
