Cells without the correct antigen proteins are foreign and are tagged with antibodies for destruction.

Answer: Option B

Explanation:

Whenever a foreign particle enters our body , our body’s own defense mechanism that is the immune system gets activated. This immune system comprises of certain antibodies that get tagged to the foreign moiety and takes it for destruction.

One more added advantage of these antibodies is that they remember the structure of the foreign particle that affected our body and thereby exerts double the force when the particle re-inters the body.

An increase in the total biomass of consumers in the world

Answer:

a decrease in the total biomass of consumers in the world

Explanation:

A decrease in carbon fixation would likely increase the amount of carbon dioxide in the air and decrease the amount of oxygen. This would change how much respiration and photosynthesis could take place, resulting in:

a decrease in the total biomass of consumers in the world,

an increase in the total biomass of producers in the world, and

a decrease in the size of insects and arthropods, since their ability to move oxygen from the air into and through their bodies is limited.

it is hard to calculate the carrying capacity of the earth because not all of the planet is inhabited and with the way that us humans can grow food practically anywhere the capacity cannot be accurately determined.

Answer:

Explanation:

Carrying capacity is the maximum members of population of species which an environment can support on the basis of presence of resources.

It is difficult to calculate the carrying capacity of planet earth for human beings. As not all land over earth is occupied by humans and the population of human beings increasing exponentially worldwide. Due to their intelligence and ability to solve problems related to scarcity of resources. The carrying capacity of humans is difficult to determine.

C. DNA molecules

Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Final answer:

The chromosomes in a cell nucleus are made up of C. DNA molecules, which contain the cell's genetic information in the form of genes.

Explanation:

Chromosomes within the nucleus of a cell are composed of deoxyribonucleic acid (DNA) molecules. Each chromosome is a single DNA molecule complexed with proteins, which include histones, that assists in the organization and compaction of these DNA molecules.

Each chromosome is a single DNA molecule wrapped around proteins. Genes are relatively short segments of DNA that contain the code for the creation of a protein. The DNA within these chromosomes carries genetic information in segments called genes, which are responsible for the inherited characteristics of an organism.

Answer: C

Cell is the membrane-bound fundamental unit of life, in which all living things are composed. All living things can be divided into three basic domains: Bacteria, Archaea and Eukarya. The primarily single-celled organisms found in the Bacteria and Archaea domains are known as prokaryotes, which are made of prokaryotic cells while organisms in the Eukarya domain are made of the more complex eukaryotic cells. These organisms, called eukaryotes, including plants, animals, fungi etc.

Prokaryotic cells do not have a well-defined nucleus but the DNA molecule is located free-floating in the cell, termed as nucleiod (an open region containing DNA). Prokaryotic cells lack certain organnelles like mitochondria, Golgi apparatus, Endoplasmic reticulum etc. which are all found in eukaryotes, the organnelles are not membrane-bound, if present.

Eukaryotic cells have a well-defined nucleus surrounded by a nuclear envelope that consists of two lipid membranes, where the genetic material is stored and different membrane-bound organnelles to perform different functions within the cell.

The answer is asexual reproduction

Brittany's new sweet potato plant grew from the root through vegetative reproduction, a process in which plants grow from parts other than seeds. Sweet potatoes have the ability to produce shoots directly from the root tissue due to their storage of starches and sugars. This type of propagation allows for the cultivation of genetically identical sweet potato plants.

The new sweet potato plant that grew from the root Brittany planted is an example of vegetative reproduction, where plants grow from a part of the original plant other than seeds. Sweet potatoes are propagated by cutting roots, which then develop new shoots. This method is especially viable in sweet potatoes because of their ability to store starches and sugars in their fleshy roots. These nutrients provide the energy needed for the direct growth of new shoots from the root tissue. Another term that is relevant in this context is adventitious roots, which refers to roots that grow from parts of the plant other than the normal root system, such as from stem or leaves.

Other starchy roots that people eat include carrots, parsnips, beets, and turnips, though these are typically grown from seeds rather than from root cuttings like the sweet potato. Sweet potatoes possess the unique ability to produce new plants through secondary growth, which supports additional storage space for nutrients.

the answer i believe  is "total number of hydrogen atoms carbon dioxide and oxygen" pls make me a brainliest

Answer:

Total number of hydrogen atoms in carbon dioxide and oxygen

Explanation:

Cellular respiration is the biochemical process that cells perform to remove energy from molecules and use that energy in their vital processes. The two main types are anaerobic breathing (without the use of oxygen) and aerobic breathing (with the use of oxygen). The cell respiration process involves several steps. Cellular Breathing is one of the main activities of cells, as it is through this process that the cell can produce energy for all its functioning.

During cellular respiration, the total number of hydrogen atoms in the water is equal to the total number of hydrogen atoms in carbon dioxide and oxygen.

The phrase mentioned refers to the cosmological principle in physics, which asserts that the universe on a large scale is isotropic and homogeneous. It helps simplify models of the universe's expansion and is a base for theories on the universe's structure and dynamics. However, it remains an assumption and may not account for all possible micro variations.

The statement you mentioned refers to the cosmological principle, a foundational assumption in the field of cosmology. This principle assumes that on a large scale, the universe is isotropic (the same in all directions) and homogeneous (having a consistent and even distribution of matter), which leads it to appear the same regardless of your observational vantage point. Having isotropic and homogeneous properties means the universe is smooth, as shown by various galaxy surveys.

This principle has played a significant role in the development of theories about the universe's structure and dynamics. For instance, it significantly simplifies models related to the universe's expansion. Concepts like Newton's laws and the law of conservation of matter do operate under this assumption, upholding the fact that the universe's behaviour can be predictable to an extent based on these laws.

Despite its broad acceptance, keep in mind that the cosmological principle is still an assumption and is subject to limitations. For instance, it does not account for small-scale local differences and potential uneven distribution of dark matter.

The large volcanic eruption was most likely the cause of the changes in species diversity in the ecosystem.

Threats to biodiversity include population expansion, pollution, and climate change. The rate of extinction of species has increased at an unheard-of rate as a result of these concerns.

The majority of the injected ash gets cleared from the stratosphere within a few days to weeks and has no effect on climate change.

Whereas volcanic carbon dioxide, a greenhouse gas, has the ability to support global warming, volcanic gases like sulfur dioxide can actually cause global cooling.

Animal and plant deaths, fish poisoning, and volcanic eruptions' disastrous effects on wildlife are just a few examples.

Therefore, in addition to displacing species, volcanic eruptions can significantly change the ecology in their immediate vicinity.

Hope This Helps!

Final answer:

The element missing from moons and planets that would make them similar to Earth is oxygen. Oxygen's prevalence on Earth contributes to water and silicate minerals, which are necessary for the planet's life-sustaining environment. Earth contains heavier elements and a rich nitrogen-oxygen atmosphere, distinct from most other celestial bodies.

Explanation:

If carbon was the most common element found in the moons and planets and we are looking for what element is missing that would make them similar to Earth, the answer would be oxygen. Oxygen is the second most abundant element in the Earth's crust and is crucial for the formation of water, which is essential for life as we know it. Earth's crust consists of approximately 28% silicon, which is also essential in forming silicate minerals. These minerals are a significant component of the terrestrial planets, which are composed mainly of rocks and metals. Earth differs from other moons and planets due to our atmosphere and the abundance of liquid water. Terrestrial planets, including Earth, are much more abundant in heavier elements like iron and silicon compared to the gas giants and their moons, which contain lighter elements like hydrogen. Additionally, Earth has an atmosphere rich with nitrogen and oxygen, which is unlike the atmospheres of most moons in our solar system, including our own Moon. The volatiles like water, which makes up our oceans, and the thicker atmosphere that retains these components, are major factors missing in other celestial bodies that make Earth unique.

The finches on the Galapagos Islands are a good example of adaptation because they all trace their ancestry into a small group of finches that inhabited these islands, but diversified in accordance to the environment. On the Galapagos Islands, there are finches that have numerous types of different beak shapes and sizes, despite them all being derived from a single group of finches that had the same characteristics. The reason for this is that once they got to these islands, there were multiple niches int the food chain that were free for taking. Some finches started to feed on plants, some on seeds, some became insect-eaters etc. Every food type needs special adaptation so that the finches can eat it more easily, or even be able to get to its nutritional part, thus their beaks started to change in accordance to their food preference.

❤Gianna❤

Answer:

1. Acid Rain matches with the first statement.

2. Eutrophication match with the second statement.

3. Biomagnification match with the third statement.

Explanation:

Acid Rain is any type of precipitation having acidic components that fall to the earth surface from the atmosphere and enter in the water cycle.

It can be dry also, acid rain affects affect living beings and water bodies in many ways.

The increase in the concentration of toxic chemicals or substances in the tissues of living beings at successively higher trophic levels in a food chain is biomagnification. The most common example of eutrophication is nitrogen and phosphorus which come from runoff from agricultural land and from detergents.

The enriched with nutrients in any body of water or lake causes the death of animal life and a dense growth of plant life from lack of oxygen.

Agriculture significantly contributes to the amount greenhouse gases emitted into the atmosphere. This is cause by several aspects of agriculture. For instance, livestock generate more greenhouse gases (methane from the wastes they produce) worldwide than all modes of motor-vehicle transportation combined. There's also the aspect of deforestation. Trees help reduce greenhouse gases in the atmosphere by taking CO2 from the air.  Therefore, cutting down trees in order to plant crops/raise livestock is indirectly adding to the amount of greenhouse gases in the atmosphere. Agriculture also requires the uses of engines to harvest and transport crops (ex: tractors plowing the soil or trucks transporting crops to grocery stores), which creates greenhouse gases as well.
