HELP PLEASEEE!! 10 points and BRAINLIEST!! 2. Honey Bees may be headed for extinction.
Why do you think this is happening? (Things
to think about: habitat destruction, erosion,
pollution, invasive species, human impact.)

Answers

Answer:

Well the most common is habittat destruction. With the number of humans only growing, more land is needed and habitat desturctions occur. Lack of food is also a problem, as some crops don’t grow as much so the bee’s food source is smaller which leaves thousands dead. Also if the food source doesn’t run out, there are pesticides sprayed and the bees will die if eaten one which the chemical properties in a pesticide will kill. Also if not used, littering, if you dump it into a water source, the water gets contaminated and the bees could die from that, or the water spreads ano the flower would receive this chemical property, which could kill the Bee’s food source, or the flower doesn’t die but when the bees consume it, the bee will die.

In the practice of ________, scabs from smallpox victims were used to immunize susceptible individuals against smallpox.

Answers

Answer: Variolation

Explanation:

Variolation can be defined as the condition in which the inocolutaion of the individuals with the infectious materials, scabs or pulses from the smallpox victim.

This was introduced by the route of nasal passage or injected intravenously. The infection that developed because of this was less than normal and it provided protein against more serious disease.

Hence, the correct answer is Variolation.

The poly(A) sequence that is added to RNA during processing: helps prevent rapid breakdown of the messenger RNA. is needed for ribosomes to attach to messenger RNA. aids in the accuracy of translation of the messenger RNA into protein. helps prevent formation of complex three-dimensional structures in the messenger RNA.

Answers

Answer:

Option A, helps prevent rapid breakdown of the messenger RNA

Explanation:

The poly-A tail is a chain of adenine nucleotides which when get attached to the messenger RNA during RNA processing enhances the stability of the molecule and therefore prevents it from breaking down. This is required because after the transcription of gene in a eukaryotic cell, newly formed RNA molecule undergoes several modifications. It also helps is preventing the new RNA from enzymatic degradation in the cytoplasm and translation.

Hence, option A is correct

The pedigree below concerns a certain rare disease that is incapacitating but not fatal. Determine the most likely mode of inheritance of this disease. Write the genotype of each family member according to your proposed mode of inheritance. If you were this family’s doctor, how would you advise the three couples in the third generation about the likelihood of having an affected child?

Answers

Males are the only ones who exhibit the condition because it is X-linked and recessive (unaffected parents have affected progeny). Given that the feature is rare, it is assumed that no one possesses it.

What is pedigree analysis?

Pedigree is a family treediagram with standardized symbols. A pedigree reveals the connections between family members.

It identifies the members of a family who have particular geneticpathogenic variations, features, and diseases as well as their current health.

Because the disease is X-linked and recessive, only males can have it (unaffected parents have affected progeny). It is considered that no one has the feature because it is rare.

When one marries into the family, they inherit the recessive allele. Because the boy inherited a Y chromosome from his father, the first couple has no chance of having a child who is afflicted.

The possibility that the secondcouple will have afflicted sons is 50%, but there is no chance that they will have affected daughters.

All of the third couple'sdaughters will be carriers even though they have no chance of conceiving an impacted child.

Thus, this can be concluded regarding the given situation.

esiska black is da right answer ahaha

Explanation:

Was the rate of increase of sucrase activity greater when sucrose concentration went from 2.5 to 7.5 g/l or when it went from 22.5 to 27.5 g/l?

Answers

Answer: It is greater when sucrose concentration went from 2.5 to 7.5g/l.

Explanation: The rate of reaction of an enzyme is known to be affected by the rate of concentration of its substrate, which in this case is the sucrose Solution.

If the rate of increase of concentration is high,the activities of the enzyme SUCRASE will increase accordingly, in order to breakdown the substrate.

The rate of increase of Sucrose from 2.5 to 7.5g/l is higher(300%) than the rate of Increase of Sucrose from 22.5 to 27.5g/l (1.22%). It is expected under circumstances that the action of SUCRASE will increase at a rate higher in the first Solution than in the second Solution.

Final answer:

The rate of increase in sucrase activity depends on the concentration of sucrose and whether or not the enzyme is saturated. The increase could be greater at lower concentrations (2.5 to 7.5 g/l) if sucrase is not yet saturated. The increase might be less at higher concentrations (22.5 to 27.5 g/l) if sucrase is near or at saturation point.

Explanation:

The increase in sucrase activity is generally considered to be a response to the concentration of substrate present, in this case, sucrose. The increase in activity happens because more substrate (sucrose) is available for the enzyme (sucrase) to act upon. However, there is a limit to this increase. Once the enzyme is saturated with substrate, further increases in substrate concentration do not increase the enzyme's activity. This is known as the saturation point.

To determine whether sucrase activity increased more when sucrose concentration increased from 2.5 to 7.5 g/l or from 22.5 to 27.5 g/l, we would need specific data on the rate of sucrase activity at these different concentrations. It's possible that the increase from 2.5 to 7.5 g/l was greater if this is in the ascending portion of the enzyme activity curve and the sucrase was not yet saturated with sucrose. Conversely, the increase from 22.5 to 27.5 could be lesser if the sucrase is near or at saturation point.
