A geneticist is studying two genes. each gene can be either dominant or recessive. a sample of 100 individuals is categorized as follows. gene 1 gene 2 dominant recessive dominant 56 24 recessive 14 6 (a) what is the probability that a random sampled individual, gene 1 is dominant (b) what is the probability that a random sampled individual, gene 2 is dominant (c) given that gene 1 is dominant, what is the probability that gene 2 is dominant
Answers
"(a) what is the probability that a random sampled individual, gene 1 is dominant" - We should first add up all of the individuals that are dominant for gene 1 (56+24) and then divide it by the total number of individuals (100).
[tex] \frac{56+24}{100} [/tex] =0.8
The probability is of 8 in 10 individuals.
"(b) what is the probability that a random sampled individual, gene 2 is dominant" - Follow the same logic as in the previous question.
[tex] \frac{56+14}{100} [/tex] =0.7
The probability is of 7 in 10 individuals.
"(c) given that gene 1 is dominant, what is the probability that gene 2 is dominant" - Because we are considering those that are dominant for gene 1, our total number of individuals is the total individuals that are dominant for gene 1 and not the whole 100. Once we have this restriction, and we want to know the probability that gene 2 is dominant in these individuals, we should also only consider those that are dominant for gene 2.
[tex] \frac{56}{56+24} [/tex] =0.7
The probability that gene 2 is dominant, given that that gene 1 is dominant, is of 7 in 10 individuals.
The probability of a random individual having dominant gene 1 is 56%, the probability of having dominant gene 2 is 70%, and the probability of gene 2 being dominant given that gene 1 is dominant is 89.2%.
Explanation:To find the probability that a random sampled individual has a dominant gene for gene 1, we need to divide the number of individuals with dominant gene 1 by the total number of individuals. In this case, there are 56 individuals with dominant gene 1 out of a total of 100 individuals, so the probability is 56/100, which simplifies to 0.56 or 56%.
Similarly, to find the probability that a random sampled individual has a dominant gene for gene 2, we divide the number of individuals with dominant gene 2 by the total number of individuals. In this case, there are 70 individuals with dominant gene 2 out of a total of 100 individuals, so the probability is 70/100, which simplifies to 0.7 or 70%.
To find the probability that gene 2 is dominant given that gene 1 is dominant, we consider only the individuals with dominant gene 1. Out of the 56 individuals with dominant gene 1, 50 individuals also have dominant gene 2. So the probability that gene 2 is dominant given that gene 1 is dominant is 50/56, which simplifies to 0.892 or 89.2%.

In order for the growth rate to remain constant what must happen to the birth rate?
Answers
Final answer:
To maintain a constant growth rate, the birth rate must be equal to the death rate, achieving a balance where the population size remains stable. This scenario is typically reached in Stage 4 of population growth dynamics, where both birth and death rates are low, hence no significant change in population size occurs.
Explanation:
In order for the growth rate to remain constant, the birth rate must be equal to the death rate. This balance ensures that the population size stays stable over time. Population growth dynamics can be understood through different stages:
Stage 1 - High birth and death rates lead to slow population growth.Stage 2 - The death rate falls but the birth rate remains high, leading to faster population growth.Stage 3 - The birth rate starts to fall, slowing the population growth.Stage 4 - The birth rate and death rate reach the same low level, resulting in zero population growth.At Stage 4, the key to maintaining a constant growth rate, which is essentially zero growth in this context, is having the birth rate decrease to match the lower death rate. This equilibrium prevents any significant increase or decrease in the total population size. Factors such as societal development, healthcare improvements, and policies like the One-Child Policy in China have been historical influencers on birth and death rates, affecting population stability.

Why do plant cells need chloroplasts? Explain.
Answers
Answer:
Plant cells need chloroplast as they are the site for photosynthesis.
Explanation:
The chloroplast is the green-colored double membrane-bound organelles present mostly in cells of leaves of green plants. Chloroplasts have chlorophyll pigments which serve to trap the sunlight for the process of photosynthesis. Both light-dependent and light-independent phases of photosynthesis take place in chloroplast to form organic sugars.
Hence, chloroplasts serve as a site for photosynthesis in plants.
Evidence that Earth’s core has a high iron content comes from the study of _____.
Answers
Evidence that Earth’s core has a high iron content comes from the study of "meteorites".
Meteorites refers to the pieces of different bodies in our solar system that make it to the ground when a meteor or "falling star" flashes through our climate at velocities of 15 to 70 kilometers for each second (approximately 32,000 to 150,000 miles for every hour). The larger part begin from space rocks broken by contacts with different space rocks. In a couple of cases they originate from the Moon and, apparently, comets and the planet Mars. Shooting stars that are found after a brilliant occasion has been seen are known as a "fall," while those found by chance are known as a "discover." Meteorites are normally named after a town or an expansive geographic milestone nearest to the fall or find, aggregately named regions. "Meteorite" can allude to an individual example, to those gathered inside a strewnfield, or to a particular territory.
which of the following terms can be defined as the movement of water across a cell membrane?
a- exocytosis
b-osmosis
c-active tranport
d-facilitated diffusion
Answers
Answer:
b-osmosis
Explanation:
Osmosis is the movement of water that occurs within cells through a semipermeable cell membrane. This process is performed from a medium with lower water concentration to another with higher concentration.
In osmosis, the solvent (water) is passed from one medium to another across a cell membrane. This process does not cause energy waste and therefore osmosis is considered a passive transport. In the osmosis process, water, which is the solvent, tends to cross the semipermeable membrane in order to balance the solution concentration. This action is performed until the osmotic pressure is stabilized.

Heritability of height is ______ if children have good nutrition and health care, but it is only ______ when they are malnourished.
Answers
Base on the researches and studies, the probability or the percentage of an individual to gain the heritability of the height is about ninety five percent, only if the individual is in good shape and in good nutrition but when a person is malnourished and weak, it will only be at twenty percent because heritability wouldn’t be applied as the body responds to a different simulation.
Final answer:
The heritability of height is higher when children have access to good nutrition and health care, underscoring the interaction between genetics and environment. Malnutrition lowers heritability, demonstrating the influence of environmental factors on physical development.
Explanation:
The heritability of height is higher if children have good nutrition and health care, but it is only lower when they are malnourished. This concept illustrates the interaction between genetics and the environment in determining physical traits like height. While genetics provide the potential for an individual's height, environmental factors such as nutrition and health care are crucial in realizing this genetic potential. Malnutrition can severely impact growth, preventing individuals from reaching the height they are genetically predisposed to. Conversely, adequate nutrition and health care support optimal growth and development, allowing the genetic factors that contribute to height to manifest more fully.
It's essential to understand that both genes and environment play significant roles in determining height. Studies estimate that approximately 60% to 80% of height variation can be attributed to genetic differences, with 20% to 40% down to environmental factors, predominantly nutrition. This interaction highlights the complexity of physical development and the critical role that a healthy environment plays in achieving genetic potential.
How can habitat corridors be beneficial to species that need large areas in which to live and move around?
Answers
Answer:
A habitat corridor is an area of land that connects to populations and is separate from all human activities such as logging. It can be beneficial because if there were two populations that needed large areas of land they could connect for an even larger area and it would prevent the damaging effects of inbreeding.
Explanation:
A habitat corridor is an area of land that connects to populations and is separate from all human activities such as logging.
What is habitat corridor?It can be beneficial because if there were two populations that needed large areas of land they could connect for an even larger area and it would prevent the damaging effects of inbreeding.
The term "corridor" is prone to misunderstanding and incorrect definition. A habitat corridor is defined by Beier and Noss (1998) as: a linear habitat embedded in a heterogeneous matrix.
A habitat corridor's significance can only be determined by the main habitat it connects. To reach their full potential, corridors depend on a network of already-existing but discontinuous natural areas (dechant).
Therefore, A habitat corridor is an area of land that connects to populations and is separate from all human activities such as logging.

A biology student wants to conduct a study of how the amount of sunlight affects the length of sleep for mice. she sets up for cages with a mouse in each cage. what are the constants? what is the independent variable? what is the dependent variable? what data do you need to collect during this experiment?
Answers
In the biology student's experiment, the constants include the cage environment and mice care conditions. The amount of sunlight is the independent variable, while the sleep length for the mice is the dependent variable. They must collect data on sunlight exposure and sleep length.
Variables in a Biology Experiment
When a biology student conducts an experiment to study the effects of sunlight on the length of sleep for mice, several components must be identified. The constants are the conditions kept the same across the experiment, such as the type of mouse, the environment within the cages aside from varying light, the mice's diet, and other care conditions.
The independent variable is the amount of sunlight that the mice are exposed to, as it is the condition being manipulated or changed. The dependent variable is the length of sleep for the mice, which is the observed outcome that may change in response to alterations in the independent variable.
To collect relevant data during the experiment, one needs to record the exact amount of sunlight each mouse receives (which potentially could be measured in hours of exposure or intensity of light) and the length of sleep for each mouse, quantified in hours or minutes of sleep.

Which of the choices listed below are characteristics shared by all epithelial tissues? 1 contain a high amount of extracellular matrix (substance between cells) 2 avascular (no blood vessels) 3 cells closely joined together 4 form surface layers 5 found immediately next to blood-vessel rich connective tissues?
Answers
Epithelial tissues are characterized by being highly cellular with little to no extracellular matrix, avascular, and having cells closely joined together. They are attached to a basal lamina and possess the ability to quickly regenerate cells.
The characteristics shared by all epithelial tissues include cells that are closely joined together, forming an impermeable barrier thanks to tight junctions, the presence of avascularity meaning they contain no blood vessels and rely on diffusion or absorption for nutrient exchange, and the fact that they form surface layers covering body surfaces and lining internal cavities.
Epithelial tissues are also directly positioned next to connective tissues rich in blood vessels. Another key characteristic is that these tissues are highly cellular with little to no extracellular matrix material between cells.
The basal lamina, part of the epithelial tissue, is a thin layer composed of glycoproteins and collagen, and it serves as the attachment site separating the epithelium from the underlying connective tissue. Furthermore, epithelial tissues are known for their ability to rapidly replace damaged and dead cells, an essential feature for maintaining the integrity of surfaces that are frequently exposed to wear and tear, such as in the airways and digestive tracts.

Answers
I just took the test the answer is (B) Physiological. I put in Biochemical the first time and got it wrong.
Answer:
Physiological
Explanation:
Physiological adaptations are adaptations that an individual undergoes during his or her lifetime and are associated with the organism's functioning in response to environmental variables - such as the monocular vision that exists in herbivores that need a broad view of their environment. These adaptations are not always passed on to offspring (in the case of monocular vision, they are). When physiological adaptation is not passed offspring is called acclimatization.
