Describe the two stage life cycle of plants: the gemetophyte stage and the sopophyte stage

Answers

Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle.

What was the health of the ecosystem of Atlas National Park like before wolves were reintroduced? *WILL GIVE BRAINLIEST*

Answers

Answer:

the populations of their prey—the deer, rabbits, and so on—may increase due to a lack of at least one natural predator.

Explanation:

Wolves are causing a trophic cascade of ecological change, including helping to increase beaver populations and bring back aspen, and vegetation. Today, nearly 25 years after wolves were reintroduced into the park, the top predators have helped parts of the ecosystem bounce back. They've significantly reduced elk herds, opening the door for willow, aspen, beaver and songbird populations to recover.

The health of the ecosystem is not good due to imbalance conditions.

The health of the ecosystem of Atlas National Park is not good before the introduction of wolves because the population of herbivore such as deer increases which leads to the destruction of all vegetation present in the park as a result the park health deteriorates.

When the wolves are introduced in the ecosystem, they controls the population of herbivores i.e. deer that feeds on the grass and the recovery of vegetation that was lost due to herbivorous animals occur so we can conclude that the health of the ecosystem of Atlas National Park is not satisfactory before wolves were reintroduced in the park.

how many codons equal one amino acid

Answers

Explanation:

hope the answer was helpful

Three codons equal one amino acid

CODON:

A codon is a nucleotide sequence consisting of three bases. The genetic code is read in a group of three nucleotide bases at a time, which are called codons.

Each codon encodes an amino acid. For example, codon AUG encodes methionine amino acid.

Each codon is read during translation to form an amino acid sequence. This means that the number of codons in a mRNA (nucleic acid) sequence determines the number of amino acids in a sequence.

Therefore, three codons equal one amino acid.

Answers

The two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.

What are proteins?

Proteins are a major group of biological macromolecules composed of a linear chain of aminoacids that are linked by means of peptide bonds.

Proteins are fundamental macromolecules present in all biological systems and they can be made by one or more polypeptides in order to form molecules that exhibit primary, secondary, tertiary, and quaternary structures.

These macromolecular structures can be evidenced by the tridimensional shapes that adopt different proteins, which can be globular or fibrous.

In conclusion, the two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.

In mice, there are three options for fur color: black,grey and white. What type of inheritance is shown by these mice?

A. Simple
B. Co-dominance
C. Incomplete dominance
D. Sex linked inheritance

Answers

Answer:

C. Incomplete dominance

Explanation:

Incomplete dominance is a type of non-mendelian inheritance in which one allele does not completely mask the phenotypic expression of the other allele in a gene, hence, the blending of both alleles give rise to an intermediate third phenotype.

According to this question, there are three options for fur color in mice namely: black, grey and white. This is so because the alleles for black and white coloration exhibits INCOMPLETE DOMINANCE, hence, they produce a third phenotype (grey) that is a blend of both parental phenotypes.
