Answer:are you asking a question?
Explanation:
Maintaining blood glucose levels is an important homeostatic activity of the body, not specifically because every cell of the body must have glucose but primarily because the brain relies on glucose for its metabolism.
a. True
b. False
Answer:
a. True.
Explanation:
Even though the cells in our body rely on glucose as a source of energy, they can replace glucose's energy with lipids or proteins' energy. In the brain's case, this is not possible since the blood-brain barrier, which is a highly selective barrier between the blood and the extracellular fluid in the central nervous system, allows the passage of glucose as the only source of energy. This is why maintaining the correct levels of glucose is crucial for the metabolism in the brain.

#carryonlearning7. Explain how the equations for photosynthesis and cellular respiration compare.
Answer: In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water. C6H12O6 (glucose) + O2(oxygen) → CO2(Carbon Dioxide) + H2O(water) + ATP energy. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

In some bunnies, the gene for fur color is controlled by condominance. The allele for gray color is G and the allele white color is W. The heterozygous phenotype results in a gray and white bunny/ What is the genotype for gray bunnies? what is the genotype for white bunnies? what is the genotype for gray and white bunnies?
Answer:
Genotype gray bunnies: GG
Genotype white bunnies: WW
Genotype gray and white bunnies: GW
Explanation:
In diploid species (2n), organisms receive one gene copy (allele) from each parent. Codominance is a relationship that occurs when both alleles of the same gene show dominance. In consequence, the expression of both alleles in heterozygous individuals results in a new phenotype. In this example, the expression of G and W alleles results in a gray and white phenotype. Examples of codominance include individuals with type AB blood group in humans or the roan coat color in horses.

Ecologists are interested in quantifying different kinds of biodiversity. In each of the two studies outlined here, which kind of biodiversity are ecologists studying?
Ecologists establish 20 small areas, called plots, randomly scattered across a California grassland. They count the number of different plant species present in each plot.
By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland.
a. Genetic diversity
b. Functional diversity
c.Ecosystem diversity
d. Species diversity
Ecologists draw blood samples from basking shark (Cetorhinus maximus) specimens caught from a single large population in the Atlantic Ocean. From each blood sample, the ecologists isolate DNA. Comparing several DNA sequences across the individuals that were sampled, the ecologists are able to estimate the variation in DNA sequences in the entire population.
a. Genetic diversity
b. Ecosystem diversity
c. Species diversity
d. Functional diversity
One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, species, ecosystems, and ecological processes play in supporting human society and a healthy biosphere. Which of the following are benefits provided by biodiversity?
a. Controlling pests
b. Providing medically useful chemicals
c. Keeping topsoil fertile
d. Eliminating the ozone hole
Answer:
1. --> d. Species diversity
2. --> a. Genetic diversity
3. --> a. Controlling pests, b. Providing medically useful chemicals , and c. Keeping topsoil fertile
Explanation:
1) Kinds of biodiversity
Genetic diversity: Among species. Refers to genes variability among species that differentiate them and allows them to adapt to different environments. The genetic charge of one species differs from other species´ genetic charge. Species diversity: Refers to the diversity of species, which can be measured by: Species richness: Number of species in a defined unit sample, Species abundance: Describe the distribution of the species abundance.Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region, or any well-defined spatial unit. It is simple and easy to interpret. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
2) Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear fresh-water, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, to learn, provides a spiritual/religious space, is a source of inspiration, it is considered to be cultural patrimony, and the source of scientific knowledge.

Newton's 2nd Law is F= ma. Write a problem that gives the mass and the acceleration of an object and asks us to find the force.
Answer:
An object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.
Given the following data;
Mass = 20kg
Acceleration = 0.5m/s²
To find the force;
Force = mass * acceleration
Substituting into the equation, we have;
Force = 20 * 0.5
Force = 10 Newton.

a. The smaller protein will migrate (move) faster relative to the larger protein in SDS-PAGE but slower in gel filtration.
b. The smaller protein will migrate (move) slower relative to the larger protein in both SDS-PAGE and gel filtration
c. The smaller protein will migrate (move) faster relative to the larger protein in both SDS-PAGE and gel filtration
d. The smaller protein will migrate slower (move) relative to the larger protein in SDS-PAGE but faster in gel filtration
Answer:
a. The smaller protein will migrate (move) faster relative to the larger protein in SDS-PAGE but slower in gel filtration.
Explanation:
Gel filtration chromatography is a technique of chromatography in which particles facilitate separation based on molecular size. The larger protein come out of the column and form gel permeation chromatograph. The smaller proteins move faster to migrate from the column.
