Traumatic injuries, such as that suffered by Christopher Reeves (an actor that portrayed Superman years ago) can affect a variety of functions of the body. The dysfunctions are dependent upon the level in the spinal cord the damage occurred and what aspect(s) of the cord is damaged. In this posting, you are to describe the organization schemes of the spinal cord (both anterior-posterior as well as internally).

Answers

Answer 1
Answer: The spinal cord is divided into 31 segments with 31 pairs of nerves exiting the cord - 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal nerve.
In respect of internal structure of the cord, there are white matter in the periphery and gray matter inside. In the center there is a thin canal filled with cerebrospinal fluid.

How many different gametes can an RRYy parent form?

Answers

An RRYy parent can form four different gametes: RY, Ry, rY, and ry.

What are gametes?

Gametes are reproductive cells that are responsible for the genetic makeup of offspring. In animals, these cells are known as sperm and eggs, and in plants, they are known as pollen and ovules.

Gametes contain half the number of chromosomes as the parent cell, allowing for genetic recombination and diversity in offspring during sexual reproduction.

A Group of students performing an experiment collect Euglena samples from a pond and keep them in darkness in a vessel containing pond water which would be the conclusion for this experiment? A) The Euglena cells remain alive because they are completely heterotrophic and feed on the organic matter present in the pond water. B) The Euglena cells die because they are completely autotrophic in nature and are unable to create food in the absence of sunlight. C) The Euglena cells, which are both autotrophic and heterotrophic, remain alive even in the absence of sunlight because they

Answers

The conclusion of this experiment would be the Euglena cells, which are both autotrophic and heterotrophic remain alive even in the absence of sunlight because they are able to feed on the organic materials that are present in the pond water. The correct option among all the options that are given in the question is the third option or option "C".

Plant and animal cells release energy stored in bonds of glucose molecules when they perform

Answers

Answer: Cellular Respiration

Explanation:

Plants and animals use cellular respiration to convert biochemical energy from the nutrients into high energy molecules known as adenosine triphosphate ans the waste product is released outside the body.

This process gives energy to the plants and animals to perform all the metabolic processes taking place inside the body.
Cellular Respiration is when plant and animal cells release energy stored in the bonds of glucose molecules.

Which structures carry out life functions within cells?

Answers

The specialized features of a cell that carry out cell functions are collectively called organelles. Examples of organelles include the nucleus, ribosomes, mitochodrion and golgi aparatus. 

Final answer:

The structures carrying out life functions within cells include organelles such as the mitochondria, peroxisomes, a cytoskeleton composed of microfilaments, intermediate filaments, and microtubules, the nucleus, and components of the endomembrane system.

Explanation:

The structures that carry out life functions within cells are often referred to as organelles. Among them, we find the mitochondria and peroxisomes which are essential for the cell's energy and detoxification processes. Mitochondria, through biochemical reactions, transform energy-carrying molecules into ATP - the cell's primary form of energy. Peroxisomes, on the other hand, detoxify harmful substances into harmless ones.

Moreover, cells possess a supportive framework, referred to as the cytoskeleton, made up of microfilaments, intermediate filaments, and microtubules. These all play unique functions, including providing a track for material transport within the cell.

In addition to these, the nucleus serves as the cell's command center, housing its DNA and controlling all cell functions. Last, but not least, we encounter the endomembrane system (including the ER and Golgi apparatus) and the cytoplasm - all essential for the cell's protein synthesis and transportation, and maintaining the cell's health and activity.
