Answer:
Cone cells help detect colors.
Explanation:
Light travels into the eye to the retina located on the back of the eye. The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors.
What is the name of the structures that
are built to recognize specific invaders
and trigger an immune response?
A. antibodies
B. antigens
C. macrophages
Answer:
C
Explanation:
Macrophages is a type of white blood cell. This basically finds out if there is an invader, and stimulates an immune response. Note that, this is not the only function of this structure.
The structures that are built to identify and recognize specific foreign agents and activate the immune system are antibodies, Therefore, option A is correct.
What are antibodies?Antibodies, also known as immunoglobulins, are Y-shaped proteins that are produced by B cells in response to the presence of specific antigens in the body, such as viruses, bacteria, or other foreign substances.
Each antibody molecule is composed of four protein chains, two identical heavy chains, and two identical light chains, that are joined by disulfide bonds. Antibodies are a key component of the adaptive immune system, which is responsible for recognizing and eliminating specific invaders.
Antibodies play a critical role in protecting the body against infections, as well as in the development of vaccines and other immunotherapies. Therefore, option A is correct.

passive transport, which means it
does not require energy.
Which of the following is an
example of facilitated diffusion?
A. liquid molecules colliding
B. plants bringing nutrients into their roots
from the soil
C. protein channels embedded in the cell
membrane
D. the sodium-potassium pump actively
bringing sodium and potassium into the cell

What is Springs structure?The Spring framework, sometimes known as Spring, has arisen as a response to all of these issues.
This framework eliminates the complexity associated in designing enterprise applications using EJB by leveraging a variety of innovative techniques, including as dependency injection (DI), aspect-oriented programming (AOP), and plain old Java objects (POJO).
Dependable, and scalable enterprise applications can be created by Java EE 7 developers using the open source, lightweight Spring framework. The primary goal of this framework is to offer you a variety of tools for managing your business objects.

Do you think human population growth is a concern in the United States? Explain your reasoning.
Answer:
In my opinion, Yes the human population growth is a concern in the United States because Human population growth impacts the Earth system in a variety of ways, including:
Increasing the extraction of resources from the environment. These resources include fossil fuels (oil, gas, and coal), minerals, trees, water, and wildlife, especially in the oceans. The process of removing resources, in turn, often releases pollutants and waste that reduce air and water quality, and harm the health of humans and other species.Increasing the burning of fossil fuels for energy to generate electricity, and to power transportation (for example, cars and planes) and industrial processes.Increase in freshwater use for drinking, agriculture, recreation, and industrial processes. Freshwater is extracted from lakes, rivers, the ground, and man-made reservoirs.Increasing ecological impacts on environments. Forests and other habitats are disturbed or destroyed to construct urban areas including the construction of homes, businesses, and roads to accommodate growing populations. Additionally, as populations increase, more land is used for agricultural activities to grow crops and support livestock. This, in turn, can decrease species populations, geographic ranges, biodiversity, and alter interactions among organisms.Increasing fishing and hunting, which reduces species populations of the exploited species. Fishing and hunting can also indirectly increase numbers of species that are not fished or hunted if more resources become available for the species that remain in the ecosystem.Answer:

Some scientists would say that nucleic acids are
the most important molecules in living cells;
others might suggest that proteins are more
important; and some might say that life could
not continue without a supply of carbohydrates.
Write a sentence in support of each of these
points of view.
Answer:
In my pov:The nucleic acids are the most important molecules in living cells beacuse It is the macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The proteins are more important because Our body needs protein to stay healthy and work the way it should. More than 10,000 types are found in everything from your organs to your muscles and tissues to your bones, skin, etc. Protein is also a critical part of the processes that fuel your energy and carry oxygen throughout your body in your blood.The life could not continue without a supply of carbohydrates beacuse Carbohydrates are important to the daily lives of living organisms. They store energy (starches), provide energy for cells (glucose), and provide structure to plants and some animals.Why does it make good metabolic sense for phosphoenolpyruvate carboxykinase, rather than pyruvate carboxylase, to be the primary target for the regulation of gluconeogenesis at the level of control of enzyme synthesis?.
Because oxaloacetate is required by the body for other metabolic pathways, it is best to regulate gluconeogenesis at the level of synthesis of phosphoenolpyruvate carboxykinase.
What is metabolic regulation?Metabolic regulation refers to the various mechanisms employed by the cells and tissues to regulate metabolic activities in the body.
One form of metabolic regulation is gene expression regulation.
Phosphoenolpyruvate carboxykinase converts oxaloacetate to phosphoenolpyruvate while pyruvate carboxylase converts pyruvate to oxaloacetate.
Since oxaloacetate is required by the body for other metabolic pathways, it makes sense to regulate gluconeogenesis by regulating level of synthesis of phosphoenolpyruvate carboxykinase.

Polygenic inheritance occurs when a trait is controlled by several pairs of genes, traits such as skin color and height in humans are the result of it.
What is polygenic inheritance?It is used to refer to the inheritance of quantitative traits that occurs when a character is due to the action of more than one gene that may also have more than two alleles.
That is, it occurs when a characteristic is governed by two or more sets of alleles, there are traits, such as weight, skin color, height, which are governed by the cumulative effect of many genes.
