Actin, myosin, and troponin are:A) ligaments
B) tendons
C) muscle protein
D) bones
E) types of ligaments

The connective tissue holding bone to bone is a;
A) tendon
B) muscle
C) smooth muscle
D) ligament
E) A and D

Answers

Answer 1

Answer:

Answer:

1. C: muscle protein

2. D: ligament

1. Actin and myosin are proteins that form contractile filaments of muscle cells. Troponin regulates muscular contraction and is found in skeletal and cardiac muscle fibers.

2. Tendons connect muscle to bone. Muscles provide movement. Smooth muscles behave involuntarily. Ligaments connect bone to bone.

Hominins first appear by around 6 million years ago, in the Miocene epoch, which ended about 5.3 million years ago. Our evolutionary path takes us through the Pliocene , the Pleistocene , and finally into the Holocene, starting about 12,000 years ago.

Select the answer option that lists the levels of genetic information in order from smallest to largest.a. genome; gene; chromosome; DNA strand
b. gene; DNA strand; chromosome; genome
c. DNA strand; gene; genome; chromosome
d. gene; chromosome; DNA strand; genome
e. DNA strand; chromosome; gene; genome

Answers

Answer:

b. gene; DNA strand; chromosome; genome

Explanation:

The smallest unit in genetic structure will be gene which is a segment of DNA. After that comes DNA strand which may contain one or more genes. A chromosome is a larger structure as compared to a DNA strand because a chromosome contains two DNA strands which are joined at centromere. All the chromosomes in an individual collectively form genome so genome is an even larger term when it comes to genetic information.

Final answer:

Genetic information can be organized from smallest to largest as follows: DNA strand, gene, chromosome, and genome. The correct answer from your list is 'b'.

Explanation:

The levels of genetic information, organized from smallest to largest, are as follows: DNA strand, gene, chromosome, and genome. Let's break it down step by step:

DNA strand: This is the smallest level and forms the building blocks of genetic information.
Gene: Genes consist of a length of DNA that codes for a specific protein or function.
Chromosome: A chromosome is a combination of many genes and is packaged into a single structure. Humans have 46 chromosomes.
Genome: The genome is the complete set of genetic material in an organism. It includes all the genes and chromosomes.

Therefore, the correct answer from your list would be option 'b': gene, DNA strand, chromosome, genome.

On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded, releasing radioactive isotopes into the air. The majority of the isotopes that were released and spreading thousands of miles were of the element iodine. As a class, discuss what endocrine glands would be most affected and how it would become apparent in the nearby population.

Answers

The thyroid gland will be mostly affected in this case. The element Iodine is

the major precursor which is involved in the formation of two hormones.

Thyroid hormones

Triiodothyronine (T3)

Thyroxine (T4).

When an individual is exposed to radioactive iodine , it alters the production

of the hormones which leads to series of effects such as:

Decreased metabolism
Low body weight
Goitre etc.

Read more about Thyroid hormones herebrainly.com/question/2469666

Answer:

In the given case, the thyroid gland will be affected the most due to the exposure of the element iodine. For the synthesis of thyroid gland hormone, T3 and T4 iodine is required. As the exposure of the radioactive iodine element is taking place, therefore, it will result in the deterioration of the thyroid gland. Radioactive iodine is generally used in the treatment of hyperthyroidism.

However, in normal individuals, the exposure of the radioactive iodine element results in a decrease in the level of thyroid hormones below the normal level due to the destruction of the thyroid cells. The symptoms seen can be neck tenderness, swollen salivary gland, and loss in body weight.
