Question 1 options: The endocrine system is a network of glands located throughout the head and torso. Unlike the nervous system

yulyashka [42]

The endocrine system is a network of glands located throughout the head and torso. Unlike the nervous system which is directly wired throughout the body, endocrine organs are separate entities linked to each other via the cardiovascular system.

What is the cardiovascular system explained?

For the body to get oxygen, blood must be pushed from the heart through the circulatory system to the lungs. Following that, the heart pumps oxygenated blood through the arteries to the rest of the body. Veins bring blood that is oxygen-deficient back to the heart, where it is circulated again.

Why is cardiovascular important?

The cardiovascular system feeds the body's cells and organs with oxygen, nutrients, hormones, and other essential compounds. The body must be capable of meeting the demands of stress, exercise, and activity. It helps control body temperature among other things.

What is the starchy material inside seeds that provides nutrients for the embryonic plant called?

PilotLPTM [1.2K]

Answer:

Endosperm

Explanation:

An endosperm develops in a seed after a process known as double fertilisation occurs in the ovary of a flower whereby one of the sperm nuclei inside a pollen grain reaches the interior of the embryo sac and fuses with the two polar nuclei forming a triploid nucleus which is the primary endosperm.

The endosperm supports embryonic growth by supplying nutrients and acting as a mechanical barrier to protect the embryo during seed development and germination.
The endosperm has living cells that regulate seed germination.
The endosperm is secreted with hydrolysis enzymes through the gibberellin hormone that induces the synthesis of amylase in the aleurone layer.
The hydrolysis enzyme catabolizes starch which act as energy source providing carbon and nitrogen for seed germination and seedling development.

What might be some challenges of working in a forensic biology lab?

OleMash [197]

Answer/Explanation:

You would have to be very careful of cross-contamination. That means you would have to work very carefully and precisely with protective clothing, ensuring that none of your DNA (from skin or hair or even trace) gets into the sample you are working with
You would have to be very careful to check and record samples properly to ensure nothing got mixed up or mislabeled and this could be disastrous for criminal cases
All the material is very precious and sometimes only one sample exists, so you have to avoid making any mistakes. Experiments can't always be repeated.
