California is home to the largest, tallest, and oldest trees on earth, all of which are gymnosperms.
Gymnosperms are plants that have seeds and are usually coniferous trees. Given that those largest, tallest, and oldest trees are sequoias, this seems to be the correct answer.
Nonvascular plants are quite small. Seedless vascular plants is also incorrect, because sequoias have seeds. Angiosperms are flowers.
I think it’s true because they contain a code with a specific protein that function s in one or more types of cells
Answer:
This definition suits that of "HOMOLOGOUS CHROMOSOMES"
Explanation:
Homologous chromosomes are similar pairs of chromosomes i.e. in length, gene positioning and centromere location (one from each parent) but not identical. Homologous chromosomes are not identical in the sense that, alleles on each pair may be different, resulting in genetic variation of the offspring.
Using humans as a case study, a karyotype (pictorial display of chromosomal arrangement) shows the complete set of chromosomes, which has two complete set (diploid). Each human cell contain 23 pairs of chromosomes, with each pair contributed by each parent i.e. 46 chromosomes in total. Every chromosome pair represents a set of homologous chromosome.
Answer:
The correct answer is option C.
Explanation:
Before meiosis, DNA that is stacked into chromosomes must replicate. Before replication, the sex cell has two copies of each chromosome, one from mother, and one from father.
DNA replication takes place in the same manner as it does during mitosis. After the chromosome replication, the homologs are double in number, and each chromosome now has a homologous pair of chromosomes.
Thus, the correct answer is option C.
The statement that may explain type II diabetes is that a protein that is normally activated by the insulin receptor does not perform its function. That is option C.
<h3>Causes of type II diabetes</h3>
Diabetes mellitus is a metabolic disorder that occurs due to the inability of the body cells to utilize the insulin produced as seen in type II diabetes or the inability of the pancreatic cells to produce insulin in enough quantity.
In type II diabetes, there is presence of insulin in the bloodstream of the patient but the body cells are not able to make use of it to metabolize glucose.
This is because when the protein that is activated by insulin receptor fails to function, problems with insulin signalling can occur which impairs the proper management of glucose levels in the blood.
Therefore, the statement that may explain type II diabetes is that a protein that is normally activated by the insulin receptor does not perform its function.
