Which nerves are the hair cells in contact with?
Answer:
Auditory nerve
Explanation:
Hair cells form synapses with bipolar neurons whose axons form the auditory nerve. Tips of the outer hair cells are attached directly to the tectorial membrane. When the inner hair cells move they make contact with the overhanging tectorial membrane
Fun fact: Hair and nials are made out of the same things!

Which of the following is *true* of the placenta? Question 18 options: 1) It fully develops six months after birth. 2) It forms during the seventh month of prenatal development. 3) It is the fluid-filled sac that houses the developing embryo and fetus. 4) It allows the exchange of nutrients between the embryo and the mother, while at the same time filtering out harmful material.
Answer:
4) It allows the exchange of nutrients between the embryo and the mother, while at the same time filtering out harmful material.
Explanation:
The placenta is an organ present in all mammals. She is confirmed between the 6th and 8th week of pregnancy and has as main function the exchange of substances between the mother and the fetus. Among these substances are nutrients, gases and even secretions. The placenta also has the function of fighting infections and promoting immunity to the fetus, in addition, it can act as the lung, the intestine and the liver, while the fetus does not develop its organs.
In the Diffusion Through a Membrane lab, the model cell membranes
allowed certain substances to pass through based on which characteristic
of the diffusing substance?
O (1) size
O (2) shape
O (3) color
O (4) temperature
Answer:
4
Explanation:
Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion

1. Which of the following most accurately complete the statement below -
An increase in biodiversity result in
A. More competition for abiotic factors
B. Less competition for biotic factors
C. An increase in the sustainability of an ecosystem
D. A decrease in the sustainability of an ecosystem
Answer:
The correct answer is - C. An increase in the sustainability of an ecosystem.
Explanation:
Biodiversity is the variety of different biological species and populations on the earth or in an ecosystem. Biodiversity helps in maintaining health by providing food and other resources. Higher biodiversity healthier the earth.
Sustainability is the ability to maintain the ecological process and its structure and function in case of external stress for a longer time. The more sustainability of an ecosystem the healthier the ecosystem. The biodiversity of an ecosystem provides sustainability to the ecosystem. An increase in biodiversity will lead to a more sustainable ecosystem.

Which of the following are shown in karyotypes?
a
sex chromosomes
b
homologous chromosomes
c
autosomes
d
all of the above
Answer:
Karyotypes describe the chromosome count of an organism and what these chromosomes look like under a light microscope. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.
Explanation:
As this karyotype displays, a diploid human cell contains 22 pairs of homologous chromosomes and 2 sex chromosomes. ... The maternal and paternal chromosomes in a homologous pair have the same genes at the same locus, but possibly different alleles.
Human blood type is determined by three alleles IA, IB, and IO. The alleles IA and IB are co-dominant to each other, and both are dominant to IO. Within a large, randomly mating population (540,000 individuals), the frequencies for the blood type alleles are 0.3 for the IA allele, 0.6 for the IO allele, and 0.1 for the IB allele. Calculate the expected numbers of people in the population having the blood type of A.
Answer:
1a. Number of people in the population with blood group A = 243000
1b. Number of people in the population with blood group B = 70,200
1c. Number of people in the population with blood group AB = 32,400
1d. Number of people in the population with blood group O = 194000
2. The percentage of type B people that are heterozygotes (IBIO) = 12%
Note: The question is incomplete. The complete question is given below:
Human blood type is determined by three alleles IA, IB, and IO. The alleles IA and IB are co-dominant to each other, and both ar e dominant to IO. Within a large, randomly mating population (540,000 individuals), the frequencies for the blood type alleles are 0.3 for the IA allele, 0.6 for IO, and 0.1 for the IB allele. a. Calculate the expected numbers of people in the population having each blood type A, B, AB, and O. b. 2. Determine the percentage of type B people that are heterozygotes (IBIO).
Explanation:
According to Hardy-Weinberg equilibrium equation, p²+q²+2pq=1
Where heterozygote allele 2pq,
p² = dominant h0m0zygous frequency
2pq = heterozygous frequency
q² = recessive h0m0zygous frequency
1a. Blood group A has two genotypes- IAIA and IAIO
The genotype frequency will be:
IAIA= 0.3 X 0.3 = 0.09
IAIO= 2 × 0.3 x 0.6 = 0.36
Total genotype frequency = 0.09 + 0.36 = 0.45
Number of people in the population with blood group A = 0.45 × 540,000 = 243000
b. Blood group has two genotypes- IAIB and IBIO
The genotype frequency will be:
IBIB= 0.1 x 0.1 = 0.01
IBIO = 2 × 0.1 x 0.6 = 0.12
Total genotype frequncy = 0.13
Number of people in the population with blood group B = 0.13 × 540,000 = 70,200
c. Blood group AB genotype frequency is 2 × IAIB x IAIB
Blood group AB = 2 × 0.3 x 0.1 = 0.06
Number of people in the population with blood group AB = 0.06 × 540,000 = 32,400
d. Blood group O has one genotype IOIO
IOIO = 0.6 × 0.6 = 0.36
Number of people in the population with blood group O = 0.36 × 540000 = 194000
2. Genotype frequency of heterozygote IBIO blood group = 2 × IB × IO
2 × 0.1 x 0.6 = 0.12 = 12%
The percentage of type B people that are heterozygotes (IBIO) = 12%
name the process through which energy is Incorporated in the ecosystem?
Answer:
photosynthesis
Energy enters the ecosystem via sunlight as solar energy. Primary producers (a.k.a., the first trophic level) turn that solar energy into chemical energy via photosynthesis. Common examples are land plants, photosynthetic bacteria and algae

#CARRYONLEARNINGwhy the solute can't move from higher concentration to lower concentration?
Answer:
yes, so when the concentration of a solute is high, the concentration of water is lowered since there is more solute per water, less water per solute. Thus, when water moves from low concentrations of solute to high concentrations of solute, it moves from high concentrations of water to low concentrations of water.

Jill is planting a garden in her yard and notices that the fertilizer she is using contains gypsum. She learns that gypsum is a rock that is mined from underground and used to make fertilizer and other products. She remembers from science class that gypsum is rated a 2 on Moh’s hardness scale. Which of these describes this rock? Choose the two statements that apply.
A. It cannot scratch any other rocks.
B. It can scratch rocks that are rated a 1.
C. It is very soft compared to other rocks.
D. It is very hard compared to other rocks.
E. It can scratch any rock rated from a 2 to a 10, but not a 1.
Answer:
B and C
Explanation:
It can scratch rocks rated a 1 but not above a 2, the scale goes to 10 so it is very soft compared to other rocks.
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?
Answer:
C- the child must have inherited the gene from both parents.
Explanation:
Both parents could carry the trait and have no symptoms, but both parents passed it down to their child causing the child to have sickle cell anemia.
