Answer:

Stomach Flu

Explanation:

Stomach flu—or gastroenteritis—is an infection of the stomach and upper part of the small intestine. Common symptoms are diarrhea, vomiting, stomach pain, and cramps.

Explanation:

The lytic cycle is one of the two cycles of viral reproduction, the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane. Now during the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages.

is this answer good enough? That’s all I know to my knowledge

A result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.

An scientific hypothesis is a given explanation to a scientific observation from the real world.

A hypothesis must be verifiable, which means that it can be confirmed or rejected by using the scientific method.

In conclusion, a result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.

Answer:

A

Explanation:

The chemical equation for cellular respiration is:

OR: Glucose + Oxygen → Carbon Dioxide + Water (+ Energy)

Since water is on the right side of this equation, it is produced as a result of the metabolic process rather than used up. So, the correct is A.

Answer:

Please find the mRNA and amino acid of the DNA sequence in the table below.

Explanation:

This question is describing the processes of transcription and translation. Transcription is the synthesis of mRNA from a DNA template while translation is the synthesis of an amino acid sequence from a mRNA sequence.

The following nucleotides combination are given in this question. Their transcription into mRNA using the complementary base pairing rule is as follows;

DNA = mRNA

- ATG = UAC

- GTA = CAU

- CAA = GUU

- AAT = UUA

- GCG = CGC

- TGT = ACA

- ACT = UGA

- CCC = GGG

- TAG = AUC

Using the codon chart attached as an image, the translation of these mRNA codons is as follows:

mRNA = amino acid

- UAC = tyrosine (tyr)

- CAU = histidine (his)

- GUU = Valine (Val)

- UUA = Leucine (leu)

- CGC = Arginine (Arg)

- ACA = threonine (Thr)

- UGA = STOP codon

- GGG = Valine (Val)

- AUC = Isoleucine (Iso)

Punnett square is given below and on the base of the result of Punnett square, Millie should mate with Denver to get three different colors of puppies.

Explanation:

The question says that Millie has a genotype BB*, which is a combination or heterozygous condition of dark brown allele B and white allele B*, now cross with Denver (light brown color):

Cross 1:

         B      B*

 B    BB   BB*

  B*  BB* B*B*

the results is : 25% dark brown, 50% light brown and 25% white.

cross 2: with Charley (white color)

    B     B*

B* BB*  B*B*

B* BB*  B*B*

there is only white and light brown puppies produced

Thus, the correct answer is - Denver.

a. They would have half chromosomes as much as the plants body cells.

b. Meiosis

Explanation:

Gametes are sex cells produced only in sexually reproducing organisms. In plants as stated in this question, male gametes are contained in pollens while female gametes are contained in ovules. The process by which these gametes are made is called MEIOSIS.

Meiosis is a cell division that reduces the chromosomal number of the parent cell by half. This means that each GAMETE will contain half the number of chromosomes as the parent cell. Fir example, if the body cell of a plant contains 30 chromosomes, each gamete formed via Meiosis in that plant will have 15 chromosomes.

In a nutshell, pollen and ovules, which are gametes of plants formed by MEIOSIS would have half chromosomes as much as the plants body cells.

Answer:

Chemical weathering is the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.

Explanation:

1. There are four types of chemical weathering: Reaction with water, Reaction with acid, Reaction with oxygen, and Reaction with organisms.

2. Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals.
