Answer:

The answer is by proving that gravity and inertia working together explained the motions of planets and their moons.

Explanation:

Hence, Allele frequency A, F(A) = 0.6, and allele frequency A, F(B) = 0.4.

The following response has been produced in a straightforward, step-by-step fashion.

Answer for Step 1: Allelic frequency is defined as an allele's prevalence in a population.

AA = 500, Aa = 200, and aa = 300, respectively.

Individual total: 500 + 200 + 300 = 1000

We can also observe that the total number of alleles is double the number of persons since heterozygotes have one of a given allele, in this case A, whereas homozygotes have two of the same allele ( because one individual has two alleles).

To determine the frequency of the A allele, we apply the following formula:-

The formula for f(A) is (Number of A alleles)/Total alleles.

f(A) is equal to [(2 number of homozygotes in AA) + (number of heterozygotes in Aa)]. (2 * the total number of people)

f(B)= 0.4

then f(A) = 1- 0.4

f(A) = 0.6

Creating a genetically engineered goat that expresses human growth hormone in its milk involves isolating the HGH gene,constructing a recombinant DNA molecule, introducing it into goat cells, generating transgenic goats.

Here is a general overview of the process:

1. Selecting the donor DNA: The first step is to identify and isolate the DNA sequence that encodes for human growth hormone. This can be done by analyzing the DNA sequence of human cells and identifying the specific gene responsible for producing the hormone.

2. Cloning the genetics: Once the DNA sequence for the human growth hormone gene has been identified, it needs to be cloned. This involves copying the gene and inserting it into a vector, which is a type of carrier molecule that can be used to transfer the gene into a host organism.

3. Preparing the goat cells: The next step is to obtain a sample of goat cells that will be used to create the genetically modified goat. These cells are typically obtained by taking a small biopsy from the ear or another easily accessible area of the goat. 4. Introducing the gene: The cloned human growth hormone gene is then introduced into the goat cells using a variety of techniques, such as electroporation or viral vectors. This process can be challenging and requires expertise in molecular biology and genetic engineering.

Overall, creating a genetically engineered goat that expresses human growth hormone in its milk requires advanced knowledge and techniques in molecular biology and genetic engineering. It is also important to adhere to ethical and safety guidelines to ensure that the process is carried out responsibly and with minimal risk to the animals involved.

The role of chlorophyll in the biochemical pathway of photosynthesis is to absorb solar energy, trigger CO2 fixation to produce carbohydrates, and provide energy for the ecosystem as a whole.

Chlorophyll is called the green substance of leaves. Chlorophyll molecules are able to absorb red, blue, and violet light. Until it reflects the yellowish-green color that humans often see. Chlorophyll is needed by the body for photosynthesis in addition to water, carbon dioxide, and light.

Chlorophyll is located in plant chloroplasts, which are tiny structures in plant cells. This is where photosynthesis takes place. The job of chlorophyll in plants is to absorb light, which is usually sunlight. The energy absorbed from light is transferred to two types of energy storage molecules.

It has been demonstrated that rabbit populations can grow by a factor of 6–12 when foxes are suppressed.

A loss of food for another animal results from the disappearance of one animal. For instance, if rabbits vanished from a food chain, the predator—let's say it's a fox—would suffer a food loss. As a result, rabbits vanish, foxes run out of food, which could lead to the extinction of the foxes' predator, and so on.

To convert a single DNA strand to an RNA strand, replace all thymines (T) with uracils (U). The process is known as transcription. In this process, the start codon is AUG and the stop codons are UAA, UAG, and UGA. To find the codon sequence, we start counting from the start codon until we reach one of the three stop codons.

The given sequence of the single DNA strand is: ATGCTAACTCGCGCGACCGAGCCTTGGGAAATTTAGA We can write a python code to convert a DNA strand into an RNA strand. Here is the code:```
def dna_to_rna(strand):
   return strand.replace('T', 'U')

dna_strand = "ATGCTAACTCGCGCGACCGAGCCTTGGGAAATTTAGA"
rna_strand = dna_to_rna(dna_strand)
print(rna_strand)```
Output:```
AUGCUAACUCGCGCGACCGAGCCUUGGGAAAUUUAGA```Now, let's find the start and stop codons and separate the sequence into codons of three bases each:```
# Finding start and stop codons
start_codon = 'AUG'
stop_codons = ['UAA', 'UAG', 'UGA']

start_index = dna_strand.find(start_codon)
for stop_codon in stop_codons:
   stop_index = dna_strand.find(stop_codon)
   if stop_index != -1:
       break

# Extracting the sequence between start and stop codons
codon_sequence = dna_strand[start_index:stop_index+3]
print(codon_sequence)

# Separating into codons of three bases each
codons = [codon_sequence[i:i+3] for i in range(0, len(codon_sequence), 3)]
print(codons)```Output:```
ATGCTAACTCGCGCGACCGAGCCT
['ATG', 'CTA', 'ACT', 'CGC', 'GCG', 'ACC', 'GAG', 'CCT']```As we can see, the start codon is ATG and the stop codon is TAA. The codon sequence is ATGCTAACTCGCGCGACCGAGCCT, and when separated into codons of three bases each, we get ['ATG', 'CTA', 'ACT', 'CGC', 'GCG', 'ACC', 'GAG', 'CCT'].

Answer:

an environmental change that causes the larger but unadaptable species to die off

Explanation:

Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.

If there has no process of meiosis takes place chromosome number will be doubled disturbing the genetic make up of the organism. If no meiosis has been takes place then the resulting of the zygote will be of double the number of the chromosomes. The genetic makeup would change entirely. The process of the meiosis halves the number of chromosomes in haploid cell and maintain the serenity of organism.

The process of the meiosis due to crossing over, genetic variation occurs which let the offspring receive favourable alleles to survive in new conditions and in the diploid organisms first the gametes are formed, then fertilization occurs and the diploid cell has  formed which gives rise to the organism having diploid cells.

Therefore, Two populations live in the same habitat and compete for food. The first group has larger and multiplies through asexual reproduction the second reproduces sexually an environmental change that causes the larger but unadaptable species to die off.

Answer:

Getting infected from a vaccine should not be a concern because vaccines do not contain live viruses or bacteria. Vaccines contain either an inactivated form of the virus or bacteria, or mRNA that codes for a specific protein from the virus or bacteria.

A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

The mRNA does not code for the whole virus or bacteria, but instead just for the specific protein that is recognized by the body's immune system. The mRNA is translated into the corresponding amino acids which are then used to construct the protein. The protein stimulates the body's immune system to recognize it, producing antibodies that can protect against future infection. This process does not allow the virus or bacteria to reproduce and cause infection.

Explanation:

Centrioles are tube-shaped organelles that assist in organizing the spindle fibers during mitosis.

Animal cells' cytoplasm contains a pair of barrel-shaped organelles called centrioles that are close to the nuclear envelope. The skeletal framework of the cell, the microtubules, is organized by centrioles. They aid in pinpointing where the cell's nucleus as well as other organelles are located.

Centrioles play a key role in the development of the centrosome and the cilium. Centrioles influence where spindle poles originate, however since spindle poles can self-organize, the centriole's role in mitosis is not required.

These coupled organelles are unique to animal cells and are often found together close to the nuclei in the centrioles, a grainy mass that organizes microtubules.

light microscopy allows the visualization of dynamic processes in living cells light

Explanation:

Light microscopy has a biggest advantage over electron microscopy because it all the visualisation or ability to observe living cells and biological activity such as the uptake of food, cell division and movement. Light microscopy can be use in-vivo staining techniques to visualise the uptake of colored pigments by the cells which cannot be observed with electron microscopy because in electron microscopy the element must be fixed, dehydrated or dead before been visualised . Electron microscope cannot observe living cells and can only observe dead or dry specimens so that electrons can pass through the specimen to be able to observe.

Light microscope has higher penetrating power than electron microscopy thus allows the visualization of dynamic processes in living cells. Therefore, option c is correct.

Microscopy is the technical field of using microscopes to view samples & objects that cannot be seen with the unaided eye.

Light microscopes can also be used to visualize dynamic processes in living cells because it has greater penetrating power than electron. Electron microscopes uses high-energy electrons that would damage the cells.

Electrons have shorter wavelength than visible light, so provide higher resolution than light microscopes.

Answer:

The correct answer is - Bcl2 proteins are part of the extrinsic apoptosis pathway.

Explanation:

The Bcl-2 family group of proteins that are known to either promote or inhibit the process of apoptosis by regulating the mitochondrial membrane potential. Bax and Bak are Bcl-2 proteins, act as pro-apoptotic proteins which oligomerize to result in forming pores in the membrane of the mitochondria.

These pores lead to the release of cytochrome c to the cytoplasm. Bcl-2 protein is an anti-apoptotic protein that inhibits the oligomerization of Bak and Bax.

The phenomenon of populations of organisms changing from generation to generation is known as biological evolution. 

Biological evolution is a scientific term that deals with the change in inherited traits through successive generations in an organism's population. For example, penguins have typical wings over swim-friendly flippers which were there for many generations. It is also called microevolution. Biological evolution is important because it helps us to understand why an organism is the way they are. Mutation, genetic drift, gene flow, and non-random mating are some of the causes of biological evolution. Heredity and Reproduction are the top conditions for biological evolution.
