As a result of the experiment scientists did with Mexican tetras, it seems likely that their first hypothesis about blindness in the tetras is right. Explain how the result of the experiment supports their first hypothesis.
The scientists' first hypothesis is that blindness gives the fish some sort of evolutionary advantage, but not directly.
The experiment was: The scientists transplanted a lens from the eye of a surface tetra embryo into the eye of a cave tetra embryo. The result was striking—the surface tetra lens into the cave tetra caused all of the surrounding tissues to develop into a healthy eye.
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.
What is a hypothesis?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.

Describe the Lytic cycle.
No dam links
Answer:
Ok here ya go
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.

Answer:
A double helix shape of DNA
Explanation:
Please help due tomorrow
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.

E)
This is a dehydration synthesis reaction
The following statements are true from the image;
Proteins are being formed.The monomer, are amino acids.Many biomolecules are naturally occurring polymer substances. In this case the biomolecule that is being formed is a protein.
A protein is composed of several peptide bonds formed from amino acids. Hence, the monomer in this case are amino acids from which polypetides and proteins are formed.

Pollen and Ovules are gametes. How many chromosomes would they have compared to the rest of the plant's body cells? What process made them that way?
Answer:
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.
Question 5 (5 points) (04.03 MC) A student made the following diagram to represent cellular respiration. Why is this diagram incorrect?
A.water is not used up during this process.
B.glucose is not used up during this process.
C. The arrow for oxygen should point in the opposite direction.
D. the arrow for carbon dioxide should point in the opposite direction.
Answer:
A
Explanation:
The chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O (+ ATP)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.

Some antibiotics work by disrupting ATP production in bacteria. Which of the following will the bacteria lack when ATP production is disrupted?
A. genetic material for reproduction
B. energy to perform life processes
C. nucleic acids to make proteins
D. cytoplasm to diffuse oxygen
When there is a lack of bacteria at the time when ATP production is disrupted so here the energy is performed. Hence the option b is correct.
Reason of lacking bacteria:At the time when there is some kind of antibiotics work is done by disrupting ATP production in bacteria.
So the lacking of bacteria at the time when ATP production is disrupted so it is because of the energy to perform the life processes.

(PLEASE HELP!!!) Suppose scientists genetically modified a species of algae to produce more oil. This algal species reproduces asexually. Will all of the offspring of the genetically-modified algae also produce more oil? How do you know?
Answer:
Yes all of the offspring of the genetically-modified algae would produce more oil.
Explanation:
When an organism is genetically-modified to reproduce asexually, it makes exact copies of itself since it is the only one passing genes whereas if normal sex were to occur and both parents would pass 50%-50% of their genes down to the child.
refer(s) to an individual's preference for emotional sexual relationships with members of the opposite sex (heterosexuality), the same sex (homosexuality), or both (bisexuality). A) Sexism B) Gender identits C) sexual identification D) Sexual orientation

what is chemical weathering? what are some facts?
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.
