Most protists are______.
A)Unicellular
B)Heterotrophs
C)Autotrophs
D)Multicellular

An ectotherm is most likely to maintain homeostasis during hot weather by burrowing underground. Thus, the correct option is A.

Homeostasis may be defined as the process that involves a condition of balance among all the body systems required for the body to survive and operate correctly.

Ectotherms are those organisms that can not be able to maintain their internal body temperature with respect to the external one.

They follow different strategies like hibernation during winters and aestivation during summers.

During hot weather, they usually undergo summer sleep by burrowing underground.

Therefore, the correct option for this question is A.

Answer:

Reptiles have dry, tough skin covered in scales, Reptiles breathe using lungs.  Reptiles’ kidneys concentrate urine.  Young reptiles develop inside an amniotic egg.

Explanation:

good luck :)

Answer:

Reptiles have dry, tough skin covered in scales, which reduces water loss. Reptiles breathe using lungs; they do not exchange gases through their skin. Their kidneys also help prevent water loss by concentrating their urine. Young reptiles develop inside an amniotic egg, which is covered with membranes and a shell to prevent it from drying out.

Complete question: Sickle-shaped red blood cells result from a mutation in the gene that codes for hemoglobin. This mutation results in sickle-cell anemia. A partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia are shown below (the diagram is in the attached file)

What type of mutation is depicted in this sequence?

Answer:

The type of mutation is known as SUBSTITUTION.

Explanation:

Sickle cell anaemia is an inherited disease caused by abnormal shape of the red blood cell. This abnormal red blood cell contains less haemoglobin and cannot transport oxygen efficiently round the body. Sickle-shaped (abnormal) red blood cells result from a MUTATION in the gene that codes for hemoglobin.

Mutation is the random changes in DNA that alters genetic information and so introduce new characteristics. The different categories of mutations include:

--> Chromosomal mutation and

--> Point mutation.

SUBSTITUTION is a type of point mutation in which one base is incorrectly added during replication and replaces the pair in the corresponding position on the complementary strand. From the diagram, a partial sequence of bases from a normal hemoglobin gene and a sequence that results in sickle-cell anemia, shows a substitution of an A for the middle T. This leads to GUA in the messenger RNA, which specifies the amino acid valine. The substitution of valine for glutamic acid at this particular position alters the chemistry of the hemoglobin such that it sticks together if it is not binding oxygen, creating sickling of the red blood cells.

Explanation:

You shouldn't exercise right after eating a large meal, as you may feel bloating or muscle cramping. It's better to eat low-fiber, low-fat, and high-carbohydrate snacks 30 to 45 minutes before exercising. This can include yogurt, fruit, granola, peanut butter, or whole-wheat toast.

Answer:

Both are similar due to origin of the membrane voltage and impulse propagation whereas both are different in their function.

Explanation:

Cardiac muscle cell are similar to a nerve cell because both have the same origin of the membrane voltage and impulse propagation also occurs in the same manner whereas, cardiac muscle cell is different to a nerve cell because cardiac muscle cells form the cardiac muscular system while nerve cells form the nervous system. Muscle cells are responsible for the contraction and relaxation of heart while on the other hand, nerve cells are responsible for the transmitting of nerve impulses throughout the body.

Ecological succession usually includes change EXCEPT for the option" A" which is the number of different kinds of plants.

Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.

Answer:

Energy and nutrients are cycled throughout all the different components of the ecosystem. The non-living components like heat and nutrients are called abiotic factors. Both biotic and abiotic factors contribute to an environment's health. Biotic factors include plant productivity and animal behavior.

The smooth endoplasmic reticulum also processes these lipids, which store energy.

Nucleic Acids: Carry genetic information or form structures within cells. Carbohydrates: storage and transport of energy and structural components.

Proteins: Many proteins are enzymes that catalyze biochemical reactions, and are vital to metabolism.
