Explain how competition for food can cause natural selection.
Answers
Answer:
Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.
For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.

Which of these is a difference between DNA and RNA?
DNA is found in the nucleus; RNA is never found in the nucleus.
DNA consists of five different nucleotides; RNA consists of four different nucleotides.
RNA is double-stranded; DNA is single-stranded.
DNA contains thymine; RNA contains uracil.
In DNA, adenine pairs with guanine; in RNA, adenine pairs with thymine.
Answers
Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

1. Which of the following events is not a source of genetic variation in eukaryotic organisms?
J. Mutation
K. Independent assortment
L. Mitosis
M. Fertilisation
Answers
Answer:
Mitosis
Explanation:
Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.

During transcription, initiation involves the attachment of RNA polymerase to the promoter and the start of RNA synthesis.
Group of answer choices
True
False
Answers
Answer:
true
Explanation:
True. During transcription, initiation is the first step in which RNA polymerase binds to the promoter region of the DNA molecule.
The promoter is a specific sequence of nucleotides located upstream of the gene that signals the start site for transcription. RNA polymerase recognizes and binds to the promoter sequence, forming a complex called the transcription initiation complex.
Once the transcription initiation complex is formed, RNA synthesis begins. RNA polymerase unwinds the DNA double helix in the region of the gene, exposing the template strand. It then catalyzes the synthesis of an RNA molecule by adding complementary RNA nucleotides to the growing RNA chain according to the base pairing rules (A-U and G-C).
So, the statement "During transcription, initiation involves the attachment of RNA polymerase to the promoter and the start of RNA synthesis" is true. Initiation is indeed the process where RNA polymerase binds to the promoter and initiates the synthesis of an RNA molecule based on the DNA template. This is a crucial step in the process of transcription, as it determines where and when the transcription of a specific gene will occur.

c. Explain how this will help to ensure that cross-pollination takes place.
d. Self-pollination does sometimes occur in primroses. Would you expect it to occur more often in pin-eyed or thrum-eyed primrose? Explain your answer.
Answers
Answer:
I dont know if i am right what about A D and B
Answer:
A-There are two different types of primrose flowers: some have a pin-eyed stigma which rises above the pollen-bearing anthers, while in thrum-eyed flowers the stigma is enclosed by the anthers. Long-tongued insects like butterflies and bee-flies visit the flowers to reach the nectar at the base of the flower-tube.
B-An insect visiting a pin-eyed flower first collects pollen from the lower anthers on the middle of its proboscis, which it then transfers to the stigma in a thrum-eyed plant, which is positioned lower down the flower tube. It's an ingenious adaptation which ensures that primroses will be successfully cross-pollinated.
C-Many plants have ensured that cross-pollination takes place by deliberately keeping male and female flowers on the same plant out of sync. In this corn plant, the pollen is ripe long before the stigmas are receptive; therefore, the only way the ovules can be fertilized is by the pollen from another corn plant.
D- When they visit a thrum-eyed plant, the pollen from the anthers, which are near the top of the tube at the entrance, attaches to the top of the insect’s proboscis. When it visits a pin-eyed flower and probes deeply for nectar, the pollen is in a perfect position to be transferred to the higher stigma of this flower. An insect visiting a pin-eyed flower first collects pollen from the lower anthers on the middle of its proboscis, which it then transfers to the stigma in a thrum-eyed plant, which is positioned lower down the flower tube. It’s an ingenious adaptation which ensures that primroses will be successfully cross-pollinated.

As a genetic counselor, you advise couples about the possibility of genetic disease in their offspring. This morning you met with an engaged couple, both of whom are phenotypically normal. The man, however, has a brother who died of Duchenne-type muscular dystrophy, an X-linked condition that results in death before the age of 20. The allele responsible for this disease is recessive. His fiancee, whose family has no history of the disease, is worried that the couple's sons or daughters might be afflicted.
Requied:
a. How would you advise this couple?
b. The sister of this man is planning to marry his fiancée's brother. How would you advise this second couple?
Answers
Answer:
a. This couple should not worry.
b. This couple should worry.
Explanation:
a. The man should not be worried. This is because he is normal (phenotypically).
b. They should be worried because the sister of the man can be a carrier of the recessive allele. If she was a carrier, then half of their male children can be affected.

Which of these is a result of crossing over?
a.) Decrease in the number of chromosomes
b.) Exchange of proteins
c.) Exchange of genetic material
d.) Increase in the number of chromosomes
Answers
The result of crossing over is the exchange of genetic material that is present in Option C because this only happens in meiosis during the prophase and results in different gametes.
What is the importance of crossing over?"Crossing over" is a process that occurs during meiosis of cell division in sexually reproducing organisms that produces gametes such as sperm and eggs. During crossing over, the genetic material in the parent cells' chromosomes is exchanged, resulting in new combinations of genes in the gametes, and the importance of crossing over is that it creates genetic diversity within a population.
Hence, the result of crossing over is the exchange of genetic material that is present in Option C because this only happens in meiosis during the prophase and results in different gametes.

What is mRNA?Messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).
It was also known that there are only four nucleotides in mRNA: adenine (A), uracil (U), guanine (G), and cytosine (C). Same three nucleotide base is also present in the DNA except thymine. Thymine is replaced with uracil in case of RNA. thus option A is correct.
