Determine if the statement is true or false, and why. “Most features are caused by a mixture of inheritance and environmental factors.”
A. False, it should read “Most features are caused by inheritance.”
B. True
C. False, it should read “Most features are caused by environmental factors.”
D. False, it should read “All features are caused by a mixture of inheritance and environmental factors.”

Answers

Answer 1

The statement is False, it should read, Most features are caused by inheritance of a character. Thus option A is correct.

What is inherited trait ?

Inheritance is defined as the transfer of genetic information from parents to their offspring.

The transferred characters or traits include eye color, hair color, and blood type.

Trait can be defined as the genetic character which can be transmitted by the parent to its offspring during fertilization.

The trait which is expressed phenotypically is called as dominant trait while the other trait which is not expressed called as recessive trait.

These variations are observed in the species due to survival benefits or genetic drift.

Acquired traits are acquired by an individual in his lifetime which is due to their own activities or external influence.

Like inherited traits, acquired traits are unable tp pass to the next generation like ability to dance, cook.

Thus option A is correct.

How do buffers play a role in
homeostasis in living things?

Answers

Answer:

Buffers are commonly used in living organisms to help maintain a relatively stable pH.

In biological systems, chemical buffers prevent sharp and sudden changes in pH.

In biology, homeostasis refers to stable conditions required for the survival of organisms.

The pH is a scale used to determine how acidic/basic water is. The pH range from 0 to 14 ( a pH equal to 7 is neutral).

In human blood normal pH is about 7.35 to 7.45.

A sudden change in this value alters and negatively affects the homeostasis of the body.

The carbonic acid-bicarbonate is the most important chemical buffer which is used for mantaining acid-base balance (homeostasis) in the blood.

The blood pH can change due to respiratory acidosis/alkalosis and metabolic acidosis/alkalosis.

In conclusion, chemical buffers prevent sharp and sudden changes in pH.

Mark Brainliest please

Poikilothermic animals include types of vertebrate animals, specifically some fish, amphibians, and reptiles, as well as many invertebrate animals.

Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. This is why most reptiles are found in hot or warm climates. Reptiles often bask in the sun to get warm.

Both reptiles and amphibians are poikilothermic, which means that they cannot regulate their own body temperatures internally as birds and mammals do.

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

What is Punnett Square?

The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.

Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.
