Which bones are most important for protecting vital organs?

Answers

Answer 1

Answer:

Answer:

The correct answer would be ribs (rib cage), skull and spine.

Explanation:

Our skeletal system provides support to the body, shapes and protects vital organs. There are three major and most important bones that protect our vital organs. These three bones are - ribs or rib cage, skull, and spine.

The rib cage or ribs protect the most important organs of the body - heart, and lungs. Ribs are attached to the vertebral column and sternum in the thorax.

Skull is also protecting one of the most important organs which are the brain. The brain is a very vital and sensitive organ. Skull is consists of twenty-two bones.

Spine has 33 vertebrae bones that interlock to form the spinal column. It protects the spinal cord, nerve roots, and other organs.

Thus, the correct answer would be ribs, skull, and spine.

Answer 2

Answer: The ribcage protects the heart and the lungs and the cranium (skull) protect the brain

How many planes of symettry can you draw through a jelly fish?A-None
B-2-5
C-1
D-More than 5

Answers

I believe that the answer is B.) 2 - 5.

My reason being is because symmetry basically means 3-D , So you are asking how many sides can you see when looking through a jelly fish.

When looking through any jelly fish you will see 2-5 sides , 2-5 because there are four ( 4 ) , There is the front , the back and also both sides so it's four ( 4 ).

That was my reason for the answer I chose.

It would be D but you will not see at lease 5 sides to a jelly fish , why? = because they don't have 5 sides , most of them are square shaped or circular.

I really hope that this helped you out a lot.

Consider the cladogram.According to the cladogram, which organisms have roundworms as a common ancestor?

Answers

The correct answer is Mollusks, Echinoderms, Chordates, and Annelids. This is basically how evolution works, at a certain point in the past, there was a transitional organism that eventually developed into roundworms and the other part of his species that was exposed to other things evolved into other transitional organisms who evolved eventually into these 4 groups.

Answer:

the answer is D mollusks, echinoderms, chordates, and annelids

Explanation:

In a sexually reproducing species, evolutioncould occur as a result of
(1) modification of genes in body cells
(2) modification of genes in sex cells
(3) increased reproduction among individuals
with identical chromosomes
(4) recombination of genes in cells reproducing
by mitosis

Answers

In a sexually reproducing species, evolution could occur as a result of Modification of genes in body cells.

Final answer:

Evolution in sexually reproducing species occurs as a result of modification of genes in sex cells. Genetic variation through mutations and genetic recombination during meiosis leads to offspring that are genetically different from their parents, providing the basis for natural selection and evolution.

Explanation:

In a sexually reproducing species, evolution occurs as a result of modification of genes in sex cells. Sex cells, or gametes, such as sperm and eggs, carry genetic information that is passed on to offspring. Genetic variation can arise through mutations or through the process of genetic recombination during meiosis, resulting in offspring that are genetically different from their parents. This genetic variation provides the raw material for natural selection and evolution.

Which could result from a person who does not finish the prescribed amount of antibiotics for an infection?

Answers

Ans. Antibiotic resistant bacteria.

If someone fails to complete the course of antibiotics for an infection, some of infection causing bacteria may survive (having a greater resistance for those antibiotics). It will lead to bacterial population in afflicted patient, with a higher resistance than normal ones.

When these resistant bacteria reproduce, infection caused by their progeny would not be treatable with same old antibiotics.
