The correct answer for this question is (A) Groups of cells form tissues.
In multicellular animals, a group of similar cells alongwith inter-cellular substances perform a specific function. Such an organization is called tissue. All complex animals consist of only four basic type of tissues. These tissues are organized in specific proportion and pattern to form an organ like stomach, lung, heart and kidney. When two or more organs perform a common function by their physical and/or chemical interaction , they together form organ system, eg., digestive system, respiratory system, etc. Cells, tissues, organs and organ system split up the work in a way that exhibits division of labour and contribute to the survival of the body as whole.
Every organism’s DNA will not look and act the exact same way. If the parent reproduces asexually is the only exception to that rule. However, if all organism’s DNA resembled and acted as a deer’s DNA, then all organisms would be deer. Therefore, there are genetic differences that separate species and ensure different behaviors from organism to organism. While the DNA will be similar by using the same four nucleic bases, there is an entirely different combination of those bases from organism to organism.
Answer:
The most likely hormone released to Gina and her body deal with this dangerous and frightening situation is the adrenaline or epinephrine.
Explanation:
Adrenaline, also called <em>epinephrine</em>, is a <u>neurotransmitter</u> secreted to the bloodstream by the adrenal gland. <u><em>Under pressure or stress</em></u>, it is considered to be a survival hormone, as it <em>triggers physiological changes </em>in the body necessary to be fast or strong.
Adrenaline increases heart beating, blood pressure, stimulates breathing and dilation of the respiratory tract. It also increases glucose concentration in blood. It is responsible for the attack, defend or escape reactions.
Answer:
probably tectonic plates would shift
Answer:
b) endomysium
Explanation:
Muscle cell also called myocyte, mmusce fiber is enveloped with thin connective tissue layer of collagen and reticular fibers which is called endomysium. Muscle fibers are organized in bundles called fascicles which are covered with the perimysium (middle layer of connective tissue).
Epymysium is irregular connective tissue that covers the whole muscle.
