Explanation:
Sickle cell anemia is caused by a mutation that alters red blood cells. HELP ME PLZZ!!!
Answer:
In Sickle Cell Anemia:
Mutation that occurs in DNA is due to the substitution of thymine base by adenine base. Change in mRNA consists of a change of the GAA codon to GUA, which codes for a different amino acid. The change that occurs in the synthesized protein is the substitution of glutamic acid by valine, the consequence of which is the structural alteration of this protein.Explanation:
Sickle cell anemia is a disease that is transmitted from parent to child in an autosomal recessive inheritance pattern. It is due to a mutation that is capable of altering the shape of the erythrocyte, as well as its ability to circulate and carry oxygen.
First, a puntual genetic mutation occurs, where the sequence of DNA bases that determines the synthesis of the hemoglobin β-chain, by suffering the substitution of thymine by an adenine: CTT → CAT.The transcription of this altered sequence to mRNA results in the change of the GAA codon to GUA, which encodes a different amino acid.Once the β-chain is synthesized, in its structure there is a change in the amino acid sequence, due to the substitution of glutamic acid by valine.The interaction of valine with the other amino acids of the protein promotes a structural change, responsible for the deformation of the red blood cell that characterizes sickle cell anemia.

Convergent evolution is a process where organisms independently evolve traits. Some molecular data place the giant panda in the bear family (Ursidae) but place the lesser panda in the raccoon family (Procyonidae). Consequently, the morphological similarities of these two species are probably due to
Answer:
analogous structures
Explanation:
Analogous structures play similar and/or identical functions in unrelated organisms. For example, moths and bats both have wings, even though they aren't related. Convergent evolution is a process that generates analogous structures in organisms that don't share a common ancestor with such structures. Moreover, homo-logous structures are shared traits between organisms that share a common ancestor. On the other hand, divergent evolution is a process associated with the accumulation of phenotypic differences between organisms within a species, which eventually lead to speciation.
Which of the following statements BEST explains the relationship between microscopic organisms like bacteria and amoebas and their environment? O Microscopic organisms do not have to compete for abiotic factors such as space or water. O Microscopic organisms are affected by changes in their nonliving environment, such as changes in temperature or pH. O None of these are true, O Microscopic organisms always take shelter in other living organisms.
Answer:
Microscopic organisms are affected by changing in thier non living environment.
Explanation:
e.g bacterial internal osmotic gradient changes due to the changing in external water concentration so as for amoeba.
1) Gregor Mendel created the law of independent assortment, that genes are distributed from parent to offspring independently of only another. Which characteristic of Meiosis primarily causes this, and what phase does it occur during?
a. Homologous pairs form and align, during Interphase
b. Crossing over occurs between Homologs, during Prophase 1
c. Meiosis enters a second round of splitting, during Prophase 2
d. Chromosomes are separated into 4 separate cells, during Anaphase 2
2) Which of the following is a Homo-zygous Genotype?
a. GG
b. Gg
c. gg
d. both A and C
3) A red flower (RR) is crossed with a red flower (rr). What are the chances for each type of offspring by GENOTYPE.
a. 25% RR, 50% Rr, 25% rr
b. 50% Rr, 50% rr
c. 100% Rr
d. 100% Red offspring
4) In Genetics, Dominant and Recessive are terms used to describe the relative strength of a specific trait. Which of the following is true for the term “recessive”?
a. Recessive genes can be masked by dominant genes
b. Recessive genes are always visible
c. In order to have a recessive trait, your parents must display that trait
d. Recessive genes show up later in life
5) Two Monsters, Hagatha and Urman, are expecting a child together. Hagatha is Hetero-zygous for Sharp claws, while Urman is Homo-zygous Recessive for Dull claws. Which of the following correctly identifies the Genotypes of both monsters? (use D or d to represent claw alleles)
a. Hagatha is Dd, Urman is dd
b. Hagatha is Dd, Urman is DD
c. Hagatha is DD, Urman is Dd
d. Hagatha is DD, Urman is dd
2 = d
3 = a
4 = a
5 = a
I am not so familiar with 1 and 3 sry
Homzygous means two identical alleles so a and c are both homzygous
recessive genes are not expressed if a dominant allele is present but with be expressed if the no dominant allele is present.
If you do a cross test you can determine the percentage.
Hagatha is heterozygous meaning non identical allele like Dd or dD and the other is homzygous recessive meaning that it has identical allele like DD or dd but it's recessive so it's dd.
I hope I helped you helped you enough

What is the function of each of these structures in the cell membrane? a) phospholipid bilayer b) peripheral protein c) integral protein d) glycolipid & glycoprotein e) cholesterol
Answer:
The correct answers are described in the Explanation section.
Explanation:
The function of the structures in the cell membrane are as follows:
a) phospholipid bilayer: comprised of fatty acids and alcohol, the phospholipid bilayer acts as a hydrophobic barrier to avoid the uncontrolled transport of molecules and ions.
b) peripheral protein: they are proteins present in the external surface of the cell membrane. This proteins form temporary bonds between the cells and other molecules, attaching and detaching at specific times.
c) integral protein: this proteins have one part of its structure in the surface and other part within the cell membrane. They have different roles, including: receptors, transporters, linkers, channels, among others.
d) glycolipid & glycoprotein: proteins that have carbohydrate-bearing portions in its extracellular environment. They maintain the stability of the cell membrane and facilitate cellular recognition.
e) cholesterol: cholesterol structure helps to the packing of the phospholipids, which restricts the passage of the molecules.

how does geographic isolation cause an increase in differences between two groups
Answer:
What was once a continuous population is divided into two or more smaller populations. This can occur when rivers change course, mountains rise, continents drift, or organisms migrate. The geographic barrier isn't necessarily a physical barrier that separates two or more groups of organisms. It might just be unfavorable habitat between the two populations that keeps them from mating with one another.
Explanation:
This is a change in genetic makeup of a population or species over time
Answer:
Mutation
Explanation:
Mutation change the genetic makeup of a population of species over time.
An example is the immunity of plasmodium parasite to chloroquine without time.
Answer: mutation

What is an event of a convention current in the air
Answer:
Convection drives the circulation of air in the earth’s atmosphere. The sun heats the air near the earth’s equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.
Explanation:
___ describes how much energy an earthquake releases
Answer:
Magnitude
Explanation:
Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.
