Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body.

The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have a child with sickle cell disease. What genes did the child inherit from the parents?
A. The child must have inherited the sickle cell gene from the mother and the normal gene from the father.
B. The child must have inherited the normal gene from the mother and the sickle cell gene from the father.
C. The child must have inherited sickle cell genes from both parents.
D. The child must have inherited normal genes from both parents.

Answers

Answer 1

Answer:

c.

Explanation:

the only way to inherit sickle cell anemia is if both parents have one gene for sickle cell hemoglobin.(one sickle cell gene from mom and dad)

Halite has a mass of 33.0 g and a displaced volume of 17 ml. What is the density of halite?

Answers

Answer:

1.94 g/mL

Explanation:

Following Archimedes' principle, the displaced volume of an object (meaning the volume of water it displaces if completely submerged in it) is equal to the object's volume.

Thus the volume of this Halite sample is 17 mL.

The density of an object is equal to the mass divided by the volume:

density = mass / volume

We input the data we know:

Density = 33.0 g / 17 mL

And calculate the density:

Density = 1.94 g/mL

What is gene expression?

Gene expression is the procedure by which genetic information is utilized in the biosynthetic pathways of a functional gene product.

This aids in allowing it to produce end products such as protein or non-coding RNA as well as, as a result, affect a phenotype.

Several factors affect gene expression, along with molecules inside the cell, mutations that cause dominant negative effects.

It also cause haploinsufficiency, signaling molecules from neighboring cells and the surrounding environment, and epistasis. Several molecules within the cell influence gene expression.

The following process accurately describes gene expression: DNA is transcribed into RNA, which is then translated into protein.

Thus, the correct option is A.

What is Nervous System?

According to biology's classical idea of the nervous system, an animal's nervous system is a highly sophisticated component that coordinates its movements and sensory data by sending and receiving signals from and to various regions of the body. In order to react to such occurrences, the nervous system and endocrine system collaborate to detect environmental changes that have an effect on the body.

Around 550–600 million years ago, worm-like invertebrates were the first to develop nervous tissue. The discovery of electrical impulses in plants and their utilization in recent decades, however, has called into question this conventional wisdom. These findings have led some researchers to suggest that plants have neural systems and that the science of plant neuroscience should be established.

Which statement about matter is NOT TRUE?

b.

Living things are matter.
c.
d. Matter is made up of atoms.

Answers

Answer:

B. "Matter exists only when you can see it."

Explanation:

Since an atom is the smallest unit of matter, both "atoms make up matter" and "matter is made up of atoms" are true.

Living things like lions or plants are made up of atoms, which is the smallest unit of matter.

This means that by the process of elimination, B. is correct.

Matter exists regardless if you can see it or not. Humans cannot see air, but it is still made up of oxygen atoms (which are matter).

natural selection favored alleles for light skin in a. south america. b. africa. c. europe. d. australia.

Answers

Option C: Natural selection favored alleles for light skin in Europe.

The theory of Natural Selection was firstly expounded by Charles Darwin. It is a key mechanism of evaluation, the change in the heritable traits, and characteristic of a population over a generation.

Natural selection favored alleles for light color skin in Europe because of the well-known correlation between skin pigmentation and distance from the equator. Relethford strongly suggests that natural selection in response to environmental factors plays an important role in the geospatial patterning of human skin pigmentation variation. The lighter level of UVR required to synthesize vitamin D, which is higher in individuals with dark color skin means the region near the equator. The European region does not receive much UVR that's why in Europe alleles of light skin are favored.

What is recombination ?

Recombination can be defined as the process where DNA fragments are under go breakage and recombined to generate new allele combinations.

This mechanism will generate genetic diversity at the gene level in which variations in the DNA sequences of various organisms will be reflected.

In the field of heredity, recombination is the process which produce gametes with new allele combinations that were absent in the gametes of previous generations.

one of the type of recombination called Intrachromosomal recombination takes place between independently assorted alleles with loci on distinct chromosomes.

Crossover occur among loci within identical chromosomes in case of intrachromosomal recombination which is essential to keep in mind that recombination takes place during meiosis in both of these situations.

which category of genetic changes does not lead to the formation of oncogenes? group of answer choices transpositions point mutations copy number changes meiotic recombination translocations

Answers

Copy number changes is considered as genetic changes which does not lead to the formation of oncogenes.

Copy number change- The cytogenetic level of resolution, known as copy number variation (CNV), involves both duplications and deletions of sequences that generally have lengths between 1,000 base pairs and 5 megabases.

Genetic Change- Genetic mutations, which occur as our cells divide and generate duplicates of themselves, are modifications to your DNA sequence.

Base Pairs- The DNA molecule is made up of two bases (or nucleotides) that contain nitrogen. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four bases of DNA (T). These bases come in certain pairings (A with T, and G with C).

what would happen to the volume of air in the swim bladder if the fish didn't change the amount of air in it?

Answers

If the fish did not change the amount of air in the swim bladder, the volume of air would decrease because the pressure inside the swim bladder would increase.

Swim bladder It is an organ present in fishes that help them to adjust their buoyancy. It is a sac filled with gas that helps the fish swim by maintaining buoyancy.Fishes can adjust, i.e., increase or decrease the amount of air present in their swim bladder to regulate the volume and the pressure in them.

There is direct relationship between the concentration of oxygen and  ATP concentration in cells because with the increase of oxygen, increase also occur in the concentration of the energy that is produced in the form of ATP. Direct relationship means if one increase the other automatically increase while on the other hand, if one decrease the other also decreases.
