Can someone help me with this question, please!!
Answer:
Genotypic- 1:1
Phenotypic- 1:1
Explanation:
For this problem, I will use the letter A to represent the alleles. The first parent's genotype would be Aa, and the second parent would be aa. Then, using a punnet square to cross the two parents the outcome is Aa, Aa, aa, aa. This means there is a 50% of a mixed individual and a 50% of a purebred recessive. Both phenotypes also have a 50% chance of being expressed. Since the percentages are equal both ratios are 1:1.

Which statement describes natural selection
Answer: You didn't put any statements lol
Explanation:
But basically natural selection is when organisms with the most favorable traits will survive and reproduce. (ex. there are 2 strains of bacteria - one that resists antibiotics and one that doesn't. The one that resists the antibiotics will strive and reproduce because that will be the more favorable trait that will be able to be inherited by future generations.)

How does population growth differ between developing countries and developed countries? What might account for these differences?
Answer:
Developing countries have a low life expectancy because things like water might be populated/scarce, the air may be polluted and immunisation might not be possible. But developed countries are more likely to have safe drinking water, and vaccines.
How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution
Answer:
Cytochrome c is known to play a role in the electron transport chain and cell apoptosis. However, a recent study has shown that it can also act as an antioxidative enzyme in the mitochondria; and it does so by removing superoxide (O2–) and hydrogen peroxide (H2O2) from mitochondria.Therefore, not only is cytochrome c required in the mitochondria for cell respiration, but it is also needed in the mitochondria to limit the production of O2– and H2O2.

All of the following can take material into cells except
O active transport
O exocytosis
O endocytosis
O passive transport
Answer:
The correct answer is - exocytosis.
Explanation:
All of the given options of the transport mechanism are the transport of the substances either into the cell or out of the cell or both. Active transport is the transport mechanism that involves the transports of substances from the lower concentration region to the higher concentration region and utilize energy.
Endocytosis and exocytosis are the forms of active transport, however, endocytosis involves taking material into the cell and exocytosis out of the cell. Exocytosis is the form of active transport as it requires energy to moving materials from within a cell to the exterior of the cell.

Define the following :
-self-concept
-self motivation
-volunteer
-self-image
-Adolescents
Answer:
Self-concept is the set of ideas that make up the image that each person has about himself, that is, it is the opinion that an individual forges about himself. That sentence carries a certain value judgment. Self-concept: set of elements that a person uses to describe himself. Self-motivation is giving the reasons, the drive, the enthusiasm and the interest that provoke a specific action or a certain behavior. Volunteer is the person who, by his own choice, dedicates part of a part of his time to solidary, altruistic action, without receiving remuneration in return. The stage that comes after childhood and that ranges from puberty to the full development of the body is known as adolescence. Self-image is the value we have in relation to ourselves.
Explanation:
Self-concept: set of elements that a person uses to describe himself. The ability to motivate yourself is what is known as self-motivation. This is an important skill, as it encourages people to continue progressing even in the face of setbacks, to seize opportunities and to show commitment to what they want to achieve. Volunteer is that person who joins an organization in a free way to help altruistically in various social activities. When we speak of self-image we refer to the image that our subconscious has of ourselves. Adolescence is understood as the period of human development after childhood and before adulthood, in which the biological, sexual, social and psychological changes necessary to form a socially mature individual and physically prepared for reproduction take place.
How the
immune system works, explain why injecting an
antigen from a pathogen would help our immune
system create "memory" of the infection but not
cause the disease.
Answer:
Our immune system produces antibodies against that antigen of pathogen.
Explanation:
Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an antigen has to be done from the childhood to prevent diseases.

In the given scenario, the relative frequency of e in a population will be It could be more or less frequent than T. The correct option is a.
What is allele?An allele is one of two or more DNA sequence versions at a given genomic location. For any given genomic location where such variation exists, an individual inherits two alleles, one from each parent.
The Hardy-Weinberg principle demonstrates that an allele's dominance or recessiveness does not determine its frequency in a population.
Thus, the correct option is a.

During cellular respiration, glucose molecules undergo a series of reactions. This process results in the formation of up to 38 molecules of high-energy ATP per each molecule of glucose. Which is the source of the energy stored in these ATP molecules?
chemical energy originally stored in the glucose molecule
potential energy from the difference in the concentration gradients of the cell
kinetic energy generated by the chemical reactions
electric current created during the destruction of electrons in the glucose
Answer:
1.Sugar bonds
2.Transport proteins
3. Digestion
4. Oxidation
explanation
Chemical energy is stored in the bonds of sugar.
The concentration gradient of a substance across the membrane represents potential energy bcz it drives diffusion.Transport proteins aids the diffusion.
Digestion converts chemical energy into kinetic energy used by cells.
When the electrons are destroyed in the glucose,Energy contained in the bonds is released in small bursts,some of it is captured in the form of ATP .'The electrons are transferred to smaller molecules known as electron carriers.The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion,called the electron transport chain.As electrons move through the electron transport chain they go from a higher to lower energy level and are finally passed to Oxygen to form water.The energy released is captured as a proton gradient which powers the production of ATP.

Which statement BEST describes the measurements he would find in the jar, in the experiment group, B, compared with the concentrations of oxygen and carbon dioxide in the classroom air?
The provided question is incomplete as the important part and group of choices was missing, however, the correct question is given below:
In an experiment, Tony placed a potted plant under a bell jar, completely sealing the jar to the tabletop. After placing a box over the bell jar for 24 hours, he measured the concentrations of oxygen and carbon dioxide in the gas in the jar. Which statement best describes the measurements he would find in the jar, compared with the concentrations of oxygen and carbon dioxide in the classroom air?
Concentrations of both carbon dioxide and oxygen decreased.
Concentrations of both carbon dioxide and oxygen increased.
Carbon dioxide concentration increased; oxygen concentration decreased.
Oxygen concentration increased; carbon dioxide concentration decreased.
Answer:
The correct answer would be - Carbon dioxide concentration increased; oxygen concentration decreased.
Explanation:
There are two major processes respiration and photosynthesis that help in the production and utilizing the carbon dioxide and oxygen in plants. In order for your plant to grow photosynthesis is the process that converts carbon dioxide into glucose and oxygen. Photosynthesis only occurs in the daylight process so the use of carbon dioxide and producing oxygen is limited.
On the other hand, respiration is a continuous process that uses oxygen and glucose to produce carbon dioxide therefore the correct answer is Carbon dioxide concentration increased; oxygen concentration decreased

How can evolutionary change in one species lead to evolutionary change in another species that it is associated with? Include an example to support your answer.
Evolutionary change in one species lead to evolutionary change in another species that it is associated with by adaptive mechanisms.
What is evolution?Evolution is a process of gradual cumulative changes which occurs in organisms over a long period of time resulting in the formation of new species.
Evolution in one species results in evolution in a closely related species. For example, the evolution of resistance by trees to insect pests results in similar evolution in insect pest for development of mouth parts that enables them to feed on the plants.
Therefore, evolutionary change in one species lead to evolutionary change in another species that it is associated with.

No
Answer:
B. People enter the coffee shop at the same rate as others leave.
Explanation:
did the test !!
The answer is B. People enter the coffee shop at the same rate as others leave.
In a reaction in dynamic equilibrium, the forward and reverse reactions occur at the same rate, meaning that the concentrations of reactants and products remain constant over time.
Similarly, in the coffee shop scenario, if people are entering and leaving at the same rate, the number of customers inside the shop will remain constant, just like the concentrations of reactants and products in equilibrium.
Option A, C, D are not a good analogy for dynamic equilibrium.
