Answer:

gases

Explanation

Answer:

D

Explanation:

When an organism reproduces, new matter is added to its ecosystem, is the correct answer.

Answer: It's is the second one. The waste materials generated by one organism are often reused by other organisms.

Explanation: Mass, or matter, is conserved in all physical and chemical changes. Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.

Answer:

Due to difference in their presence in the body.

Explanation:

Errors that occur during meiosis are present in all cells of the body because meiosis cell division occurs in the sex cells of an organisms so that the errors are effects all the cells of that organism, while on the other hand, errors that occur during mitosis may occur in only a small number of cells because mitosis cell division occurs in the somatic cells so the errors are present in some body cells so we can conclude this errors in meiosis affect all cells whereas errors in mitosis affect less number of cells.

Answer:

separation of homologous pairs at anaphase I of meiosis.

Explanation:

Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend or influence the allele of another gene in the same gamete. This random distribution can only be applied to independent genes. These genes segregate independently after crossing over because they are located far away from each other.  

When cell division is going on by meiosis, it involves the random and independent segregation of the alleles. During anaphase I (meiosis), the pairs of homologous chromosomes separate independently of each other. Each integrant of the homologous pair migrates to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. The process is as follows.    

During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. During anaphase I, each of the homologous chromosomes migrate to the corresponding pole. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.

Answer:

D

Explanation:

1. protists have nuclei

2. plants don't move independently

3. animals don't make their own food

so option D is the best option

good luck

The following claims correctly describes a kingdom of Domain Eukarya is  Kingdom fungi includes organisms that get energy by decomposing materials in their environment.

Fungi are heterotrophic and eukaryotic organisms that can be unicellular or multicellular. The vast majority of species are filamentous, and these filaments are called hyphae. Some fungi are formed by several densely packed hyphae, which form the so-called mycelium.

The Fungi Kingdom is represented by unicellular or multicellular eukaryotic organisms, being found in the most diverse types of environments. Fungi include mushrooms, molds, wood ears, lichens, among other organisms.

Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility. On the other hand, fertilisers harm these microbes and cause health issues in the consumers since they are synthesised chemically.

Answer:

The Atlantic ocean is the saltiest

Answer:becuase

Explanation:

Answer:

 two cell divisions happen throughout the overall process, so a result of four haploid cells are produced.

Explanation:

A because it consists of two nuclear divisons resulting in four nuclei that are usually turned into four new haploid daughter cells

Answer:

protease

Explanation:

A protease (also called a peptidase or proteinase) is an enzyme that catalyzes (increases the rate of) proteolysis, the breakdown of proteins into smaller polypeptides or single amino acids

Answer:

A

Explanation:

independent variable is the one variable changed and tested

Answer:

A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base. Meanwhile, larger mutations can affect many genes on a chromosome. Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences.

Explanation:

Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations. Mutations can be introduced due to mistakes made during DNA replication or due to exposure to mutagens, which are chemical and environmental agents that can introduce mutations in the DNA sequence, such as ultraviolet light. Some mutations do not result in changes in the amino acid sequence of the encoded protein and can be described as silent mutations. Other mutations result in abnormal protein products. Mutations can introduce new alleles into a population of organisms and increase the population's genetic variation.

I think it's the second option

Correct me if i'm wrong but i hope i helped! xoxo

Answer: When an atom that has lost an electron comes in contact with an atom that has gained an electron, usually the the two atoms would attract each other and form a compound. This compound would be ionic since it is governed by ionic bonding.

Explanation:

Answer:

Cheaper to purchase than organic

Nutrients are concentrated, only small amounts needed

Nutrients are quickly available for plant absorption

Answer:

They're faster acting than organic making them a good choice for aiding plants in severe distress from nutrient deficiencies. These fertilizers, which come as dry, granular pellets or water-soluble products, also provide even, consistent feeding.
