Answer:
The electron has a negative charge. The electron is smaller than the other particles and can be found outside of the nucleus, which is another name for the center of the atom. In the center, there are protons and neutrons. The neutron have no charge but weigh a lot compared to the electron. The proton has a positive charge. In order to get the atomic mass, add the number of protons and neutrons together.

Fifty years ago, bed bugs were nearly eliminated in the United States by using of pesticides like DDT. Today bed bugs are back in beds and theaters. DDT is no longer used due to environmental issues. Pyrethrums are currently the top choice for bed bug infestations. Pyrethrums are especially useful to us because they generally have a stronger effect on bugs than on humans and animals.
Some bed bugs had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemically resistant offspring. How can this be explained?
Question 5 options:
bed bugs chose other bugs to partner with who had the mutation
mutations involved in the genetic variation of the bugs were chosen by them
bed bugs chose other bugs to partner with who had no mutations
mutations involved in the genetic variation of the bugs are random
d
Explanation:
i looked up and it said mutation random

Two heterozygous parents have ___________chance of contributing one of their alleles to each offspring
Answer:
Two heterozygous parents have a 50% chance of contributing one of their alleles to each offspring.
Explanation:
Individuals who are heterozygous for a specific trait have two different alleles in the gene that determines that trait. This characteristic makes their chances of contributing each of their alleles to the offspring 50%.
The alleles of a gene are distributed in the gametes by the process of meiosis, which results in daughter cells with half the genetic charge, so each gamete can only have one copy of the allelic pair of a gene.
On the other hand, if an individual has two equal alleles for a characteristic in a gene, he has a 100% chance of passing that allele on to his descendants.
How much ATP is produced in 5 molecules of glucose in the presence of oxygen in an obligate aerobe?
Answer:
190 ATP molecules
Explanation:
Cellular respiration is the process whereby energy (ATP) is obtained in the cells of living organisms by breaking down glucose molecules. Cellular respiration can either be aerobic or anaerobic depending on whether oxygen is present or not.
In the presence of oxygen, aerobic respiration, which consists of three stages namely: glycolysis, Krebs cycle and oxidative phosphorylation, is employed. Per glucose molecule;
- Glycolysis produces 2 ATP molecules,
- Krebs cycle produces 2 ATP molecules
- Oxidative phosphorylation produces 34 ATP molecules
Hence, in total, 38 ATP molecules is produced per glucose molecule in aerobic respiration. According to the question, 5 molecules of glucose will yield 5 × 38 = 190 molecules of ATP.
What are the PRODUCTS (what is made) of aerobic respiration?

Answer:
species
Explanation:
According to the most widely used species definition, the biological species concept, a species is a group of organisms that can potentially interbreed, or mate, with one another to produce viable, fertile offspring.
This level of organization is the most specific and includes a group of individual organisms that resemble one another closely and are able to interbreed to produce fertile offspring is species
what is the level of organization in an organism ?Cellular organization is one of the characteristics of a living organism which states that each living organism is made up of a single cell or more than one cell.
It is made up of various components such as chemicals like micro molecule that form the macro molecule, at chemical level the structural composition are organized together to make cells
At Cellular level of organization form the tissue and it is complex to cell but simpler to organ which makeup of various together.
The cluster of interacting organs is necessary as the organ which are the structural level that individuals do the specific function.
Organs are gather together form organ system and it is a complex system made up of organs that are similar in their function.

Answer:
Codominance
Explanation:
That would be Codominance. Codominance means that neither allele can mask the expression of the other allele (Both are dominant alleles, no recessive alleles). This is because the flower isn't only red or only pink. It has both alleles (which causes the red and pink stripes).

Answer:
a.
mutualistic root-dwelling fungi that help plants obtain more water and nutrients.
Mycorrhizal fungi are mutualistic root-dwelling fungi that help plants obtain more water and nutrients. The correct option is a.
What are mycorrhizal fungi?Mycorrhiza is helpful fungi that grow in close proximity to plant roots and get their moisture and nutrients from the soil in return for sugars from plants. By acting as root system extensions, mycorrhiza considerably expands a plant's absorptive area.
A symbiotic relationship between fungi and plant roots is known as mycorrhizae. Their main function is to increase the host plant's intake of nutrients and water by utilizing more soil than roots alone can.
Depending on the host plant and fungus' taxonomy, mycorrhizae can take on a variety of shapes.
Therefore, the correct option is a. mutualistic root-dwelling fungi that help plants obtain more water and nutrients.
