The biomass of producer is higher than the population of catfish.
Sunlight regulates the productivity of algae by allowing the algae to make their own food through the process of photosynthesis. This algae better the quality of water, provide oxygen for the aquatic organism and food for many herbivore aquatic organism.
Algae needs sunlight, carbondioxide and water for the process of photosynthesis. Catfish population in the pool increases as the biomass of algae increases because more food is available for the catfish which allows them to grow and increase their population.
In pyramid or trophic levels, the biomass of algae and other plants are the largest which is present at the bottom whereas as we go in the trophic level, population of organisms increases so we can conclude that biomass of producer is higher than the population of catfish.

Diploblastic and triploblastic embryos.
During embryogenesis, diploblasts develop two embryonic germ layers: an ectoderm and an endoderm or mesendoderm. Triploblasts develop a third layer—the mesoderm—which arises from mesendoderm and resides between the endoderm and ectoderm.

According to the model represented in the diagram, which of the following would cause the cell to not express the lacZ, lacY, and lacA sequences?
A. Binding the RNA polymerase to the gene
B. Removing the Inducer
C. Preventing the repressor from binding to the lac operon
Answer:
the answer would be a
Explanation:
When the inducer is removed from the lac operon model, then this will result in hindering the expression of lacZ, lacY, and lacA sequence in the cell. Thus, the correct option is B.
What is lac operon?Lac operon is a model which contains genes that are involved in metabolism of the cell. The genes are expressed only when the lactose is present in the medium and glucose is absent. The lac operon is turned on and off in response to the glucose and lactose levels in the medium: catabolite activator protein (CAP) and lac repressor. The lac repressor is responsible for blocking the transcription of the operon.
The lac operon can be switched off i.e., the expression of genes can be stopped by removing the inducer molecule from the medium.
Therefore, the correct option is B.

which graphic organizer best compares the energy inputs and outputs of cellular respiration and photosynthesis?
Answer:
glucose and oxygen is used for the input cellular respiration while carbon dioxide and water is used for output cellular respiration
Light energy → photosynthesis → chemical energy → cellular respiration → chemical energy is the best compares the energy inputs and outputs of cellular respiration and photosynthesis.
Thus option B is correct.
What do you mean by energy transfer ?In a living cell the energy can only transfers from one cellular reaction to another by changing its form from one type of energy to another.
photosynthesis and cellular respiration are two closely related opposite cellular reaction.
In photosynthesis light energy from sun can be absorbed by chlorophyll pigment, then conversion of inorganic matters to organic matter.
It stores energy in the form of chemical energy called glucose.
In cellular respiration, products of photosynthesis that is glucose and oxygen converted in the carbon dioxide and water with release of ATP stores a high amount of energy.
Thus option B is correct.

A growing community considers building a new hospital closer to residential neighborhoods. This will get residents to emergency care faster and save lives when it is needed. The only land available near residential areas is a forested wetland that supports a variety of species. What is a political consequence of not using the land for a new hospital?
Emergency care is farther away, risking the health and well-being of a growing community.
Preserving the ecosystem may upset residents in a community with a hospital shortage.
If there are fewer hospitals, it can slow down the number of new medical career opportunities.
It protects the lives of species and prevents a reduction in carbon sequestering by the trees.
A political consequence of not using the land for a new hospital is that preserving the ecosystem may upset residents in a community with a hospital shortage.
A very important consideration when citing infrastructure is the environmental impact of such projects. This is because, infrastructure is built on land at the expense of the ecosystems that survive in such habitat. Building the said hospital is going to have the negative impact of decrease in biodiversity.

Which molecule made during photosynthesis is the best source for carbon and hydrogen atoms used for cellular activities?
O carbon dioxide
O oxygen
O sugar
water
Answer:
carbon dioxide
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Dr. Jekyll isolated a mutant yeast cell that contained histone resistant to acetylation. What phenotype will be in those cells
According to the scenario, the mutant phenotype will definitely express a low level of gene expression.
What is meant by Phenotypes?The phenotype may be defined as the expression of genotypes in the form of traits. In a more simple sense, phenotypes may be characterized as the morphology or physiology which comes due to the combination of alleles.
The acetylation of histones leads to epigenetic modification through which the architecture of chromatin and the regulation of gene expression are controlled by chromatin structure. But when the mutant cells are resistant to these histone acetylations, it will eventually lower the gene expression through which normal functions so the gene must be affected.
Therefore, the mutant phenotype will definitely express a low level of gene expression.

Height in humans of polygenic traits with a distribution similar to the graph shown each is true concerning the distribution of heights in human populations?
Answer:
A polygenic trait is one whose phenotype is influenced by more than one gene. Traits that display a continuous distribution, such as height or skin color, are polygenic. The inheritance of polygenic traits does not show the phenotypic ratios characteristic of Mendelian inheritance, though each of the genes contributing to the trait is inherited as described by Gregor Mendel. Many polygenic traits are also influenced by the environment and are called multifactorial.Explanation:

Identify a biome and explain how the biotic and abiotic factors affect the biodiversity in that Biome? How are the biotic and abiotic factors related?
Answer:
A large community of plants and animals in a major habitat, such as a desert or a forest. Abiotic factors, such as rain, temperature and sun affect the biome drastically. If there is more rain, there will likely be more plants and animals able to live in that area. If it is hotter and sunnier, less plants and animals will be able to live in the area. Biotic factors, such as beavers in a forest can also change the biodiversity of the area. Beavers create dams which slow the movement of water. This allows other animals that can't swim against strong currents to live in the ponds and lakes the beavers make. This would be impossible if the beavers weren't there.
