glutamate is the neurotransmitter released at the rod-bipolar cell synapse. when there is light, the rod membrane potential will

Answers

When there is light, the rod membrane potential will hyperpolarize due to the release of glutamate at the rod-bipolar cell synapse.

In the dark, rods are depolarized and continuously release glutamate onto bipolar cells, inhibiting their activity. When light enters the eye and is absorbed by the rod photoreceptor cells, a cascade of events occurs, leading to the closure of sodium channels and hyperpolarization of the rod membrane. This hyperpolarization reduces the release of glutamate from the rod cells onto bipolar cells.

With decreased glutamate release, bipolar cells become disinhibited and can transmit signals to downstream cells in the visual pathway. Therefore, in the presence of light, the rod membrane potential will hyperpolarize, resulting in a reduction of glutamate release at the rod-bipolar cell synapse.

(c) Based on the data, describe the time period during which Chlorella approximates exponential growth. Based on
the data and assuming logistic growth, describe the time period during which the Chlorella population has reached
the carrying capacity of the culture. Based the data, calculate the growth rate per day for the 5-day period with
the greatest growth rate.

Answers

Populations that experience a logistic growth model depend on the density and available resources. A) 5 - 10 days. B) 25 - 30 days. C) 0.27 x 10⁶cells/mL/day

What is the logistic growth model?

In a logistic growth model, the population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases.

The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.

Assuming that the population size is N, when

N<K, the population can still grow. N approximates to K, the population's growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.  

The sigmoid curve represents the logistic growth model.

In the example,

Between 0 and 5 days the population remains relatively stableBetween 5 and 10 days Chlorella approximates exponential growth.Between 10 and 20 days Chlorella experiences exponential growth. Between 20 and 25 days the population is near the K and decreases its growth rate.From 25 to 30 days, the population reached the equilibrium point, and got to stabilize.  

Time period during which Chlorella,

          A) approximates exponential growth ⇒ Between 5 and 10 days

Between 10 and 20 days its already exponential growth.

         B) has reached the carrying capacity of the culture ⇒ 25 to 30 days

Finally,

        C) Growth rate per day for the 5-day period with the greatest growth rate.

First we need to figure out during which period Chlorella experiences the  greatest growth rate. To do it, we just need to make the following substraction,

Growth rate per period = final concentration - initial concentration

Period 0-5 ⇒ 0.08 - 0.01 = 0.07Period 5-10 ⇒ 0.55 - 0.08 = 0.47Period 10-15 ⇒ 1.9 - 0.55 = 1.35Period 15-20 ⇒ 2.8 - 1.9 = 0.9Period 20-25 ⇒ 3.2 - 2.8 = 0.4Period 25-30 ⇒ 3.2 - 3.2 = 0  

Now we know that during the period from 10 to 15 days, the population experienced its greatest growth rate. But this rate is acchieved in 5 days. Now we need to find out the growth rate per day. So all we need to do, is to divide the result of the substraction per 5 days,

1.35 x 10⁶ / 5 days = 0.27 x 10⁶ cells/mL/day

The answer is 0.27 x 10⁶ cells/mL/day

How do you suppose changes in DNA lead to speciation

Answers

Answer:

The correct answer is - change in DNA is called mutation which is essential for evolution including speciation.

Explanation:

A mutation is a change in the genetic or hereditary material which is DNA. A mutation is the main reason behind the evolution of the organism or species and speciation can be led by evolution, which takes place by results in the accumulation of many small changes in DNA or genetic changes in a population over a long period of time.

Mutations that change in DNA are required for the evolution process they are the raw material of genetic variation. without changes in hereditary material, there is no speciation or evolution possible.

Name 4 morphological and 2 behavioral traits that can distinguish between a seal and a sea lion.

Answers

Answer:

#HEY MATE HERE IS YOUR ANSWER#

Explanation:

Both seals and sea lions, together with the walrus, are pinnipeds, which means "fin footed" in Latin.

But seals' furry, generally stubby front feet — thinly webbed flippers, actually, with a claw on each small toe — seem petite in comparison to the mostly skin-covered, elongated fore flippers that sea lions possess.

Secondly, sea lions have small flaps for outer ears. The "earless" or "true" seals lack external ears altogether. You have to get very close to see the tiny holes on the sides of a seal’s sleek head.

Third, sea lions are noisy. Seals are quieter, vocalizing via soft grunts.

Fourth, while both species spend time both in and out of the water, seals are better adapted to live in the water than on land. Though their bodies can appear chubby, seals are generally smaller and more aquadynamic than sea lions. At the same time, their hind flippers angle backward and don't rotate. This makes them fast in the water but basic belly crawlers on terra firma.

Sea lions, on the other hand, are able to "walk" on land by rotating their hind flippers forward and underneath their big bodies. This is why they are more likely to be employed in aquaria and marine shows.

Finally, seals are less social than their sea-lion cousins. They spend more time in the water than sea lions do and often lead solitary lives in the wild, coming ashore together only once a year to meet and mate.

Sea lions congregate in gregarious groups called herds or rafts that can reach upwards of 1,500 individuals. It's common for scores of them to haul out together and loll about in the sand, comprising an amorphous pile in the noonday sun.

4. mRNA translation and epigenetic inheritance
5. alternative mRNA processing and chromatin compaction.
Please help to choose the best answer.

Answers

Prokaryotes regulate gene expression at 1. mRNA transcription level.

Prokaryotes largely control mRNA transcription when it comes to controlling gene expression. Prokaryotic gene regulation entails regulating the start of transcription by enhancing or impairing RNA polymerase's affinity for the promoter region of the gene. The binding of transcription factors, presence of activators and repressors, and presence of certain DNA sequences are only a few of the techniques used to achieve this control.

Prokaryotes also have other levels of control of gene expression, including as mRNA translation, mRNA processing, chromatin compaction, and epigenetic inheritance, although these levels are not as important as mRNA transcription in terms of primary regulation. These extra degrees of control over gene expression are more typical of eukaryotic cells.

Which of the following best explains why ligase is required for DNA replication?
Ugase facilitates the binding of RNA polymerase to the promoter region.
Ligase enables the newly synthesized DNA to twist into a double helix
Ligase forms the hydrogen bonds between complementary bases in the two strands of DNA
The lagging strand cannot be replicated continuously, and ligase is needed to join the fragments

Answers

The lagging strand cannot be replicated continuously, and the need for ligase to join the fragments best explains why ligase is necessary for DNA replication. Here option D is the correct answer.

DNA replication is the process by which a cell duplicates its DNA prior to cell division. It involves the synthesis of two new strands of DNA, the leading strand, and the lagging strand. The leading strand is synthesized continuously in the 5' to 3' direction, whereas the lagging strand is synthesized in short fragments called Okazaki fragments.

The lagging strand is synthesized in the opposite direction of DNA unwinding, making it necessary to synthesize it discontinuously. As the replication fork progresses, short Okazaki fragments are synthesized in the 5' to 3' direction away from the replication fork. However, these fragments are not yet connected to form a continuous strand.

This is where ligase comes into play. Ligase is an enzyme that plays a crucial role in DNA replication by catalyzing the joining (ligation) of the Okazaki fragments on the lagging strand. It forms phosphodiester bonds between adjacent nucleotides, sealing the gaps between the fragments and creating a continuous, double-stranded DNA molecule.

Which term best describes the number of calories the body uses at rest?
A. basal metabolic rate
B. resting caloric count
C.resting heart rate
D. body mass index

Answers

The correct option is (a). The term that best describes the number of calories the body uses at rest is basal metabolic rate (BMR).

The term that best describes the number of calories the body uses at rest is basal metabolic rate (BMR). BMR is the amount of energy that your body requires to maintain basic functions like breathing, circulation, and maintaining body temperature while you are at rest. It's influenced by factors such as age, gender, weight, body composition, and genetics. Basal metabolic rate (BMR) is a measure of how many calories the body uses when at rest. The basal metabolic rate is the minimum number of calories the body requires to sustain its vital functions, including heartbeat, respiration, and maintenance of body temperature, while at rest. This is typically measured while you are awake, but relaxed and in a fasting state. Basal metabolic rate (BMR) refers to the amount of energy that your body requires to maintain basic functions while at rest, and it is influenced by several factors. BMR accounts for around 60-70% of your total daily energy expenditure, which means that it plays a significant role in weight management. For instance, if you have a high BMR, you will burn more calories even when you are not active, which can help you lose weight or maintain a healthy weight. However, if you have a low BMR, you will burn fewer calories even when at rest, which can make it harder to lose weight.To calculate BMR, one needs to take into account their age, gender, weight, height, and body composition. The formula used to calculate BMR is different for men and women.

For instance, for men, the formula is BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years).

For women, the formula is BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years).

Knowing your BMR can help you determine how many calories you need to consume daily to maintain your weight or achieve your weight loss goals.
