Answer:
Statements thar are true:
Some organisms have phenotypes that make them better increase chances of reproduction.
Natural selection continues to occur even today
Phenotypes found In the most successful members of a species become the most prevalent after several generations.
Explanation:
It is not true that all organisms must compete for survival, sometimes the conditions are good and there is enough food or good climate conditions and that makes no need of competition an increase in the individuals of the species.
Animals undergo natural selection, this is a random natural phenomenon that can make plants and animals adapt better or worse to the enviromental conditions. This cause that the beneficiaries can adapt, survive and reproduce and became the most prevalent after generations.
Mutations are not phenomen that occur because the living being needs it, but rather they are phenomenon that occur at random at any time and determine the possibility of survival.
A decrease in food availability will do the contrary, decrease the variation in a population because it makes that only those who manage to adapt to eat another food survive, for example.

Explain how damaged DNA in a stem cell could cause a large impact to an organism
DNA damage can affect normal cell replicative function and impact rates of apoptosis (programmed cell death, often referred to as 'cellular senescence'). Alternatively, damage to genetic material can result in impaired cellular function, cell loss, or the transformation of healthy cells to cancers.
At a fair or circus, some performers and clowns take long balloons and fold them into animals and objects as toys for children. Which statement explains why the balloon can fold, twist, and bend without bursting?
A. There is no matter that exists inside a balloon, so there is nothing that can cause the balloon to burst when it is folded, twisted, and bent.
B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.
C. The balloon is made of a flexible material so it can be changed into different shapes without ever bursting.
D. The balloon is filled with air, which is a mix of gases. The pressure of the air inside the balloon makes it rigid enough to look like an animal.
Good Luck :D ! Subject: Science
The statement which explains why a balloon can fold, twist, and bend without bursting is: B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.
A balloon can be defined as a flexible rubber bag that can be inflated with a gas such as air.
Generally, air can be trapped in a balloon by sealing its neck tightly.
Hence, this makes it possible for performers and clowns to fold, twist, and bend an inflated balloon into animals and objects as toys for children.
A inflated balloon can be folded without it bursting simply because air is fluid and as such, it would move around the inside of the balloon as it is folded.
In conclusion, air, which is a mixture of gases would move around the inside of the balloon as it is folded because it is also a fluid.

Which type of mutation reverses the direction of parts of a chromosome?
Deletion
Duplication
Inversion
Translocation
Answer:
Its "C" Inversion
Explanation:
I took the test and got it correct
Type of mutation reverses the direction of parts of a chromosome is inversion. The correct answer is option C.
What is the basic structure of chromosome ?The chromosomes are thread like structures present in the nucleus and the these chromosomes carry the genetic information in them from one generation to another.
Inversion inverts the structure of chromsome and it basically turns the chromsomes inverted.
Inversion is the process where one arm of the chromosome gets detached from the basic structure and it gets attached in the inverted direction.
This creates multiple copies of DNA turning it into genetic material and one of the X linked recessive disorders is haemophilia in which same type of mutation caused by the chromosome at the 8th position takes place.
Therefore, Mutation that reverses the directions of the part of the chromosome.

What are Leukocytes?
Leukocytes are the white blood cells. These are a type of specialized cell type which is present in blood along with erythrocyte and plasma. Leukocytes are primarily responsible for protecting the body from pathogens and germs by producing antibody proteins which fight against these organisms.
Leukocytes are irregular in shape. They can change their shape to engulf or kill the bacteria which enters the blood to prevent disease. Erythrocytes change their shape which allows them to pass through the capillaries which are very tiny.
Therefore, the correct option is B, D, and E.

The gallbladder provides ________ that aid(s) in transport of lipids across the intestinal membrane.
The gall bladder provides bile salt.
The gall bladder is a small pear-shaped organ that is located at the abdomen inferior to the liver.
This organ stores and releases the bile salt produced from the liver.
The bile salt is released through the bile duct into the duodenum of the small intestine.
The bile salt is use to emulsify fat thereby aiding it's transport across the intestinal membrane.
Therefore, the gall bladder provides bile salt that aids in transport of lipids across the intestinal membrane.

Do turtles have exoskeleton?
Answer:
Mark me brainliest (⌒▽⌒)Explanation:
The turtle shell isn't like any other protective element of any living animal: it's not an exoskeleton, like some invertebrates have, nor is it made of ossified scales like armadillos, pangolins, or some snake and reptile species. ... The turtle shell is actually a peculiar evolution of a turtle's bone structureNo. Turtles are vertebrate animals with internal skeletons. Even the shell is made of bone covered by a thin layer of tissue and keratin scutes (material similar to your fingernails). The entire skeleton is on the inside. A turtle’s shell is no more an exoskeleton than your own skull is.
