Answer:
This question lacks options: 1) keystone species. 2) symbiotic species. 3) sympatric species. 4) allopatric species. 5) refugistic species. The correct answer is 1) keystone species.
Explanation:
Keystone species are the species that have a more important effect on the ecosystem than expected for its low biomass, exerting a direct influence on the others, that is, a key species can have different effects on its ecosystem or on other species with those that cohabit. Among them are: Modification of the landscape, source of food, generators of shelter, altering ecological processes. This makes their presence very meaningful.

Which is not a major difference in the organization or content of prokaryotic and eukaryotic genomes?
a) Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.
b) Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.
c) Most prokaryotic genomes are contained in one chromosome; most eukaryotic genomes are contained on several.
d) In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements. of the above are true
Answer:
All of the above are true
Explanation:
Organisms possess two types of genome viz; prokaryotic genome and eukaryotic genome. The eukaryotic genome is possessed by cells with a well-defined nucleus, where their genetic material (DNA). The prokaryotic genome, on the other hand, lacks a membrane-bound nucleus. The major organization or content between these two genomes are:
- Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.
- Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.
- Most prokaryotic genomes are contained in one circular chromosome while most eukaryotic genomes are contained on several linear chromosomes.
- In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements.
Based on this, all of the above options are TRUE

One function of the carbohydrate macromolecule is to store energy. Which other macromolecule also functions in storing energy?
Yes, it is true that carbohydrate is a macromolecule whose function is to store energy. However, Lipid is another macromolecule whose function is also in storing energy because lipids yield more fatty acids as compared to carbohydrates.
Although, Lipids are considered to be a very crucial and great source of energy because it yields more fatty acids in comparison to carbohydrate, and also lipids are very compact in structure and highly soluble, due to which they can store energies quite efficiently.
Therefore, Lipids are macromolecules whose function is the same as carbohydrates, that is, to store energy because lipids are highly soluble and can be transferred from one cell or place to another easily and serve energies to cell molecules for metabolic activities.

ATP and photovoltaic cells are similar because they both produce chemical and electrical energy.
ATP- A vital "energy molecule" present in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it's a coenzyme that transfers energy to cells by generating its phosphate groups when it interacts with enzymes like ATP triphosphatase. ATP is generated when the particular wavelength of the light fall on the chlorophyll which converts the light energy into chemical energy.
Photovoltaic Cells- Photovoltaic systems (PV) cells use the light energy from the sun to create a electrical current by absorbing the light energy. A single solar cell has several PV cells, and the total current produced by all of these cells when combined is sufficient to power the various destinations.

Which type of cell is found in the hypodermis?
Answer:
The hypodermis contains the cells known as fibroblasts, adipose tissue (fat cells), connective tissue, larger nerves and blood vessels, and macrophages, cells which are part of the immune system and help keep your body free of intruders.
Explanation:
The hypodermis is made up of fibroblasts, these cells are a part of the body's connective tissues. These secrete collagen proteins that help in maintaining the structural framework of body.
What is Hypodermis?
The hypodermis is the bottom layer of the skin in the body. It performs many important functions such as storage of energy, connecting the dermis layer (upper layer) of the skin to the muscles and bones underneath, insulating the body during different temperature range and protecting the body from harm which could happen due to injury. As a person age, the hypodermis decreases in size, and the skin starts to sag and becomes more vulnerable to harm and injury.

What is it called when NADP+ becomes NADPH?
Answer:
This process is called phosphorylation(addition of phosphate) and since the energy comes from photons, this process is termed as photophosphorylation. Yes, the same NADPH donates its hydrogen to combine with CO2 to form glucose (C6H12O6) to become NADP again.
Explanation:
Answer:
The two reactions use carrier molecules to transport the energy from one to the other. ... The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH. When NADPH gives up its electron, it is converted back to NADP+.

Apply the law of segregation and the law of indepen-dent assortment by giving an example of each.
An example of the application of Independent assortment is that gametes will have the same probability to inherit a specific genotype for petal color.
What is Law of segregation?This law states that during meiotic division, pair of alleles segregate which leads to one allele being present in each gamete of the organism involved.
An example of this law is that if a plant has two versions of an allele for the color of furs, such as black color allele and white color, then each of the gametes will have either black or white allele only.
Law of independent assortment on the other hand deals with alleles of genes getting sorted into gametes independently of one another and there is a uniform probability.

Removing glucose molecules from the soil
this is 02.05 plant growth in agriscience foundations 1 flvs
Answer:
Altering the amount and intensity of light that plants receive
Explanation:
Altering the amount and intensity of light that plants receive will drive the rate of reactions of photosynthesis in the plants. This will in turn will lead to plants having a greater capability for yielding more food or fruits through photosynthesis.
However, this altering of the amount and intensity of light in plants should be done adequately, as excessive lighting will reduce the rate of photosynthesis in plants.

What are the functions of circulatory system?The blood circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate.
The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).
