Answer:
Land plants get the water they use in photosynthesis from the soil through their roots.
Land plants obtain water for photosynthesis from the soil, which is absorbed through their roots and transported to the leaves through the xylem.
Land plants obtain water for photosynthesis primarily from the soil. The process involves a series of steps that enable water uptake and transportation within the plant. First, plant roots, equipped with root hairs, extend into the soil and absorb water through osmosis. This occurs because the concentration of dissolved substances, such as minerals, in the root cells is higher than that in the surrounding soil.
Water moves from the roots to the xylem, which is a specialized tissue responsible for transporting water and nutrients throughout the plant. This upward movement is facilitated by a combination of root pressure, capillary action, and most importantly, transpiration. Transpiration is the loss of water vapor from the plant's leaves through small openings called stomata. As water evaporates from the leaf surfaces, it creates a negative pressure gradient that pulls water up through the xylem from the roots.
Once water reaches the leaves, it is utilized during photosynthesis. The water molecules are split during the light-dependent reactions, releasing oxygen as a byproduct and providing electrons for the production of ATP and NADPH, which are essential for the light-independent reactions (Calvin cycle).
In summary, land plants rely on their roots to absorb water from the soil, which is subsequently transported through the xylem to the leaves where it is utilized in the process of photosynthesis.

For Monsters, having One eye is dominant to having 2 eyes.
If both mom and dad are heterozygous for the number of eyes, what is the possibility of them having an offspring with TWO eyes?
Question 1 options:
0%
25%
50%
75%
100%
Answer:
About 50% I’d say because you never know if one could have two eyes or one
Explanation:
If both mom and dad are heterozygous for the number of eyes, then the possibility of them having offspring with TWO eyes will depend on the dominance relationships and if this is a monogenic trait (none of the options are correct).
How we can determine the genetic likelihood for a trait?We can determine the genetic likelihood for a trait by recognizing the dominance relationships, in the case that 2 yes is a recessive then the likelihood to have a child with this trait is 25 % (it is the likelihood of occurrence of the trait in homozygosis).
Therefore, with this data, we can see that we can determine the genetic likelihood for a trait we need to know dominance relationships.

16. Why is nitrogen only found in the blood during deep sea diving?
The following four elements are essential for gas diffusion into the alveoli:
Alveolar-capillary membrane thickness,Available surface area for gas exchange: Gases' partial pressure gradient: Gases' solubility How would a patient with this disease handle walking up the stairs?Pulmonary fibrosis is an illustration of a disease state that might develop when one of these important components is altered. Scarring causes the alveolar-capillary membrane to thicken in this disease, which affects gas exchange. Hence, individuals with pulmonary fibrosis may have breathing problems and shortness of breath, especially after exercise like climbing stairs.
In order to maintain ventilation, the chemoreceptors in the carotid and aortic bodies would be in charge of the patient.
As a result of the high pressure of the compressed air used in scuba diving, nitrogen is only found in the blood during deep sea diving. The nitrogen in the compressed air dissolves into the bloodstream when a person dives deep underwater because of the increased pressure.

When a genotype-coded phenotype is not always expressed despite the genotype's presence, the statement is untrue.
Phenotypes are they always manifested?Completely dominant alleles will always be expressed in the phenotypic of the cell. However, sometimes an allele's dominance is only partially complete. When a cell is heterozygous (having both a dominant and a recessive allele), it might exhibit intermediate characteristics.
Do phenotypes and genotypes correspond?Development + Genotype = Phenotype (in a given environment). We are interested in the relationship between these two in order to consider them in the framework of evolutionary biology. The genotype determines the phenotype in a strictly "genetic" sense.

Explain how diffusion restored homeostasis during the dialysis treatment.
During dialysis, diffusion facilitates the movement of waste products and excess fluids out of the blood, restoring homeostasis.
During dialysis treatment, diffusion plays a crucial role in restoring homeostasis. Homeostasis refers to the body's balanced state, where the levels of various substances are maintained within a narrow range. In the context of dialysis, diffusion refers to the movement of solutes across a semipermeable membrane.In hemodialysis, the patient's blood is circulated through a dialyzer, which contains a semipermeable membrane. On one side of the membrane, the patient's blood flows, while on the other side, a dialysate fluid flows. Due to a concentration gradient, solutes like urea, creatinine, and excess electrolytes in the blood diffuse across the membrane into the dialysate fluid.This diffusion process helps remove waste products and excess fluids from the blood, bringing it closer to the normal physiological range. By restoring the balance of solutes and maintaining proper fluid levels, diffusion in dialysis aids in restoring homeostasis and promoting the overall well-being of the patient.For more such questions on Dialysis:

Using water more efficiently _______.
a.
protects the environment
b.
causes the loss of natural pollution filters
c.
increases water contamination
d.
all of the above
Answer:
a. protects the environment.
Explanation:
Using water efficiently means using it wisely and not wasting it. When we use water more efficiently, we reduce the amount of water we consume, which helps to conserve water resources. This is important because water is a limited resource, and by using it efficiently, we can ensure enough water is available for future generations.
By using water more efficiently, we can also protect the environment. Water is essential for many ecosystems and habitats, and by conserving water, we can help maintain the balance of these ecosystems. Additionally, using water efficiently can reduce the need for energy-intensive water treatment and distribution processes, which can help reduce greenhouse gas emissions and mitigate climate change.
So, using water more efficiently helps protect the environment but also helps conserve water resources for the future.

Explanation:
The positive controls are those groups in the experiment whose treatments are expected to confirm previously known results, thereby enabling the comparison of these results with the target group. In this case, both active activators and repressors are able to give results that can be compared with the test group
The negative controls are those experimental groups where no response is expected. In this case, both inactive activators and repressors, and cAMP (which is a secondary messenger in diverse biological processes but is not involved in this pathway), are not expected to produce any measurable response.

It is True that the specific immune response is a selective immune response that kills pathogens by marking them for the body to target
Both macrophages and cytotoxic T cells participate in cell-mediated immune responses to eradicate infected cells and intracellular pathogens, respectively. After being activated in response to an antigen, the proliferation and differentiation of naive T lymphocytes is an initial immunological response. In order to participate in the cell-mediated immune response, a naive T cell must first come into contact with the antigen in order to be stimulated to multiply and differentiate into cells that may assist in the elimination of the antigen. To prevent the infection from spreading, killer T cells will attack any infected cell that is carrying a foreign antigen.
