Pleaseeeeeeeee helpppp meeeeee
Answer:
D.
Explanation:
For two organisms to breed successfully and produce viable offspring that are fertile, both must belong to the same species with the same number of chromosomes.
Postzygotic barrier often occur when two organisms of different species and chromosomes numbers mate. If successful, the hybrid they produce remain sterile. This is what happens when goat with chromosome number of 60, mates with sheep with chromosome number of 54.
Postzygotic barrier is responsible for the sterility of the hybrid they produce, as a result of difference in chromosome number between sheep and goat.

Why does a floating leaf indicate that photosynthesis is occurring?
Answer and Explanation:
A floating leaf indicates that photosynthesis is occurring because it means the leaf is producing oxygen, a biproduct of photosynthesis. It is possible that photosynthesis is occurring in a leaf that is not floating because it's possible that the leaf is denser than the solution and can't float.

How would a change to the sequence of nucleotides in a DNA segment affect the mRNA transcribed from the DNA?
Answer:
It would change the nucleotide sequence of the transcribed mRNA
Explanation:
During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.
In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.
Answer:
A change of the sequence of nucleotides in a DNA segment is called a mutation. This could change whether certain proteins are made that support the body or not.

What are the parts and functions of the human brain
Answer:
⭐⭐<==================>⭐⭐
☢ the brain which control and co-ordinate the body of the human being.
↪ the brain is broadly divided into three parts.
➊. cerebrum (fore brain)
➋. midbrain.
➌. hindbrain.
------------------------------------
➊. cerebrum; it is the main part of the brain so it is the faculties of learning reasoning memory, personality, intelligency, thoughts, sensation, action and all voluntary movement.
this part of the brain works according to the receptors. they have both areas such a sensory area and motor areas.
➋. midbrain; this brain controls the cerebral reflex moment. such as the visual auditory stimuli.
➌. hindbrain; it consists into 3 parts such as pons, cerebellum and medulla.
★ pons; Pons located lower part of the brain near the pituitary gland, which regulates the respiration.
★ cerebellum; it maintain the balance of the body. it accurate the movement,also control the smooth movement such as walking, dancing, riding a bicycle etc.
★ modulla: it also located the lower part of the brain which controls the involuntary action such as Heartbeat, breathing,blood circulation, blood pressure, coughing,sneezing etc.

c. Degradation of linker DNA yields DNA fragments of about 145 bp.
d. DNA binding to histones has the same effect as positive supercoiling.

Which of the following is not a line of evidence supported by empirical evidence?
a. How similar DNA is between organisms
b. The length of the organism's life
c. Where fossils are found
d. How similar the organisms were as embryos
Answer:
B
Explanation:
The length of the life of the organism is not an evidence supported by empirical evidence.
Empirical Evidence:
These are the evidences that are based on the experiments and the observation rater than the logic or theory.
The empirical evidences the same for the all observers.
For example-
Similarity of the DNA between the organisms is purely conclude after the experiments. It is always same for the all observers.
The length of the life of the organism can not be clearly predictive it can vary for different observers.
Therefore, the length of the life of the organism is not an evidence supported by empirical evidence.

On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles A and a, and the second locus has alleles B and b. A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results:
Muppet hair color as a function of two-locus genotypes
Two-locus genotype Muppet hair color
A_B_ Cookie monster blue
aaB_ Elmo red

Group of answer choices
represses gene transcription and promotes mRNA translation.
determines which end of the egg will become the head and which end will become the tail.
is found only in adult somatic cells.
Answer:
represses gene transcription and promotes mRNA translation.
Explanation:
Homeotic gene refers to any group of genes that controls the pattern of formation of body structure during early embryonic development of organisms. These genes encode proteins which is called transcription factors that direct cells to form various parts of the body. Homeotic genes is the master control genes that regulate other groups of genes that are responsible for the development of body parts that will develop in different locations.

Explanation:
When exercising routinely, timing the food that you eat around your exercise activities is important. Carbohydrate intake is particularly influential, with different ideal timings for simple carbohydrates and complex carbohydrates. The best types of carbohydrates to eat during and/or immediately after exercise are simple carbohydrates, whereas complex carbohydrates are ideally consumed a couple of hours before exercise. Complex carbohydrates take longer to digest and enter the bloodstream and can help build glycogen stores.
Sort the following food items into their respective bins based on whether they are simple, complex, or noncarbohydrate-rich foods.
Drag the appropriate items into their respective bins

how do you make yourself a better friend .
Answer:
Well we all know the way too overused/ cliched phrases like ”Be your self” or “Always be there for you friend when you need it“ Or even “your friend will be there for you no matter what”. Well I don’t think those are key things. Here’s my list that I have ought to keep since middle school.
1) DONT LIE, this is the most common thing in my opinion. Friends tell lies, and you tell lies. Thats not how friendship works. I wouldn’t even white lie on most occasions due to the fact that if a friend comes in with the worst hair cut you have ever seen in your life, they know it themselves its bad, you don’t gotta make it worse by saying it looks great. Follow the laws of rhetoric to make things play out better then a white lie or even the truth (Art of convincing). Adress the situation, then explains the outcomes and side with hem saying whatver but not main points, just common ones and visible ones, then come up with a resolution, (in these cases just tell em don’t worry about it, it’ll all blow away when _______ (thing that happened).
2) Don’t use money to buy friends, seriously don ‘t. They’ll see you as a free bank and things will only go downhill form there.
3) Never steal or hurt your friend in any way.
4) Sure do what both of you guys or more like but sometimes explore other things, discover new ways and stronger ways to bond. Maybe sucking up to go on a roller coaster or even taking a hit for your friend while playing paint ball.

What do digital signals turn sounds into?
-analog signals
-interference
-continuity
-zeros and ones
Digital signals transform sounds into zeros and ones.
Zeros and ones or binary code?Digital sound is all that sound placed on media encoded in binary code. This encoding transforms the microphone signal into a digital code that follows various parameters such as Nyquist's theorem, sample rate, bit depth, bit rate, dithering, etc.
Whit this information, we can conclude that digital signals transform sounds into zeros and ones(binary code).
