Answer:

In Amoeba and Paramoecium, osmoregulation occurs through contractile vacoule. Osmoregulation is a phenomenon in which contractile vacuole plays an important role in maintaining the water balance of the cell. Paramoecium contains two contractile vacuoles which have fixed position.

Answer:

In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets. The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the white cells).

Answer:

Hybrid

Explanation:

An HYBRID is a product of crossing two purebred organisms for a particular trait. In more genetic terms, hybrid contains two different alleles in its genotype; one from each different parent. For example, crossing a horse and a donkey will result in a mule.

Based on the above explanation of a hybrid organism, one would realize that in terms of genotype, an hybrid is usually heterozygous for the involved gene. That is, the genotype will contain one allele from each parent e.g. Aa or Dd. For instance, when crossing two purebred organisms (red, RR and white, rr) for color in four o'clock plants, the resulting organisms are heterozygous pink (Rr) and can be said to be a HYBRID.

Answer: usually from carbs

Explanation:

We should note that the function of the ATP molecule is simply for the storage of energy. In a case whereby the ATP molecule loses a phosphate group, energy is being released from it which is used for cellular processes.

Our body get the energy for reattaching a third phosphate to ADP, creating ATP usually from carbs. Therefore, the correct option is B.

Answer:

PART 1: AAAGTTGCTGGTTG

PART 2:UUUCAACGACCAAC

PART 3:

UUU ---> Phe

CAA ---> Gln

CGA ---> Arg

ACC ---> Thr

AAC ---> Asn

PART 4: AAAGUUGCUGGUUG

Explanation:

Hello There!

PART 1: The first thing we want to do is find the complementary base pairs for the given DNA strand

Remember

The base pairs are

Adenine and Thymine

Cytosine and Guanine

The DNA strand given is

TTTCAACGACCAAC

Now we pair each nucleotide with its complementary base pair

T would change to A

A to T

C to G

and G to C

leaving us with

AAAGTTGCTGGTTG

PART 2: Now we want to transcribe the complementary DNA strand

IMPORTANT NOTE: Transcribing is pretty much like the first part, pairing each nucleotide with its complementary base pair except Adenine changes to Uracil not thymine

so adenine (A) changes to uracil (U)

thymine (T) to adenine (A)

guanine (G) to cytosine (C)

cytosine (C) to guanine (G)

AAAGTTGCTGGTTG

*transcribe*

and we're left with

UUUCAACGACCAAC

The next step is to pair the codons to its corresponding amino acid using the codon table provided below

The first thing we want to do is spread the codons out

Remember codons are a set of 3 nucleotides

Codon 1 (UUU) Codon 2 (CAA) Codon 3 (CGA) Codon 4 (ACC) Codon 5 (AAC)

Now we want to match each codon with its corresponding amino acid

Going from inside to outside using each letter we get that

UUU codes for Phe (Phenylalanine)

CAA codes for Gln (Glutamine)

CGA codes for Arg (Arginine)

ACC codes for Thr (Threonine)

AAC codes for Asn (Asparagine)

PART 4 Finally we want to find the anticodon of the mrna

Which is pretty much pairing each nucleotide base with its corresponding pair

Adenine to Uracil

Uracil to Adenine

Cytosine to Guanine

Guanine to Cytosine

So we'd go from UUUCAACGACCAAC to

AAAGUUGCUGGUUG

Answer:

A

Explanation:

Antibodies are not stored in vacuoles. They are found in the blood, lymph, and other body fluids. Hence option D is correct.

Antibodies are proteins that are produced by plasma cells in response to an infection. They bind to specific antigens on the surface of pathogens, which helps to destroy them.

The other choices are all true about antibodies.

A. They are proteins. Antibodies are made up of amino acids, which are the building blocks of proteins.

B. They destroy pathogens. Antibodies bind to specific antigens on the surface of pathogens, which helps to destroy them.

C. They are produced by plasma cells. Plasma cells are a type of white blood cell that is responsible for producing antibodies.

Therefore, option D) They are stored in vacuoles is correct.

Answer:

Competition can lead animals to form new habits and adaptations they never had before this is all because of the diversity of animals in our environment and their needs to survive. :)

Explanation:

hawks and owls feed on similar prey. To avoid competition, owls have adapted to be nocturnal, hunting only at night, thus avoiding direct competition with the hawk.

Answer: A. lichens have fungal hyphae that are efficient at absorbing water and minerals to support mutualistic cyanobacteria.

Explanation:

Photosynthesis, is referred to as the process whereby there's transformation of light energy to chemical energy by green plants and some other other organisms.

We should note that for lichens, they can do photosynthesis in harsh habitats such as on the surface of rocks, where there is no soil and little water because they have fungal hyphae that are efficient at absorbing water and minerals to support mutualistic cyanobacteria.

Therefore, the correct option is A.

Answer:

Humans have two kidneys and each kidney is supplied with blood from the renal artery. The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney.
