Answer 1

Answer:

A compound light microscope is a microscope with more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen.

The scanning electron microscope (SEM) produces images by scanning the sample with a high-energy beam of electrons. As the electrons interact with the sample, they produce secondary electrons, backscattered electrons, and characteristic X-rays.

Explain the difference between exponential growth models and logistic growth models and insert a picture of each model.

Answers

Answer:

When the per capita rate of increase ( r) takes the same positive value regardless of the population size, then we get exponential growth. When the per capita rate of increase ( r) decreases as the population increases towards a maximum limit, then we get logistic growth.

Explanation:

Exponential population growth: When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.

When the stimulus voltage is increased, _______. sodium permeability into the cell decreases sodium permeability into the cell increases to overcome the potassium exiting a greater-than-threshold depolarization results a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.

Answers

Answer:

a greater-than-threshold depolarization results and sodium permeability into the cell increases to overcome the potassium exiting.

Explanation:

The occurrence of action potential requires the existence of active voltage-dependent channels to open and close in response to the membrane depolarization.  

When depolarization reaches and supers the threshold point, voltage-dependent Na+ channels open and the ion gets into the cell. The entrance of Na+ decreases the electric charge difference between the cellular interior and exterior. Membrane depolarizes and produces the action potential that tends to reach a potential equilibrium for Na+ = +60mV. The higher the Na+ input is, the greater is the depolarization and the greater is the Na+ permeability.

Once Na+ channels are closed, voltage-dependent K+ channels open, increasing the membrane permeability to the ion, letting K+ get out of the cell, following the electrochemical gradient.  

The closure of Na+ channels and opening of K+ channels are responsible for membrane repolarization.

When 2 or more organisms compete for the same resource there can be a variety of outcomes. What would be one of those outcomes?

Answers

Answer:

The biology branch deals with the relations between and physical environment of organisms.

Explanation:

The principle of competitive exclusion states that if two species occupy the same niche, they cannot exist together (competing for identical resources). Two species whose niche overlap can evolve to have different niches through natural selection, resulting in the distribution of resources.

In ecology, interspecific competition is a form of competition where individuals from different kinds compete in an ecosystem for the same resources (e.g. food or space)... There may be interspecific competition if people of two separate species share a limited resource within a single area.

In the early days of the solar system, many planetesimals orbited the Sun. The theory has it that one large planetesimal the size of Mars struck a glancing blow to the molten Earth. How did this event contribute to the formation of the Moon?

Answers

Answer:

This event led to the breaking away of a part of earth and the part was held on by earth’s gravity and this part became the moon.

Explanation:

The formation of moon was after the formation of the earth. In the initial years of the formation of earth it was affected by several asteroid hits and comets. Small planets referred to as planetesimals  also kept continuously affecting the earth. Before 4.5 billion years ago a planetesimal which was about the size of Mars hit earth.

This hit led to the breaking away of a part of earth. The part which was sent to space by the hit was caught by the gravity of the earth and the part started orbiting around the earth. The similarity of the rocks in moon to that of earth is attributed to the fact that moon was actually formed from earth.

The moon and earth keeps influencing each other. The moon’s effect reduced the speed of earth’s rotation and the moon keeps moving away from the earth due to the influence of earth.

Answer:Molten rock broke off from Earth following the impact. The rock coalesced (gathered) into a ball, which formed the Moon.

A. Have the people on the dance floor choose a partner.
B. Have more people get on the dance floor.
C. Have some people get off the dance floor.
D. Have the people on the dance floor move faster.

Answers

Answer:

it's either C or D

The students simulate a situation that might cause the reaction rate to decrease, such as having some people leave the dance floor while others move more quickly. So, the correct options are C and D.

What is Reaction rate?

The pace at which a chemical reaction occurs is known as the rate of the reaction. It is proportional to the rise in product concentration per unit time and the fall in reactant concentration per unit time. Response times can differ wildly.

For instance, because it happens quickly, wood burning has a fast reaction rate, whereas iron rusting has a low rate of the reaction because it happens gradually.

For the aforementioned illustration, the students act out a scenario that can result in a slower reaction time, such as having some participants leave the dance floor whereas others move more swiftly.

Therefore, the correct options are C and D.

What is the structure of a Triglyceride?
A. A glycerol head with 3 fatty acid tails
B. 3 Glycogen heads connected to a Hydroxyl tail
C. 3 Hydroxyls connected to a glyceride
D. A glycerol head with 2 fatty acid tails

Answers

Answer:

A. A glycerol head with 3 fatty acid tails

Explanation:

One glycerol attached to 3 fatty acids each

The structure of a Triglyceride is  a glycerol head with 3 fatty acid tails. Hence the correct option is A.

The structure of a triglyceride consists of a glycerol molecule bonded to three fatty acid tails. Glycerol is a three-carbon alcohol with a hydroxyl group attached to each carbon, while fatty acids are long hydrocarbon chains with a carboxyl group at one end. Through a condensation reaction, the hydroxyl group of each glycerol molecule combines with the carboxyl group of a fatty acid, resulting in the formation of an ester bond.

This process is repeated three times, with each fatty acid binding to a different carbon of the glycerol molecule, thus forming a triglyceride. The three fatty acid tails provide energy storage and insulation properties, while the glycerol molecule serves as a backbone for their attachment. Triglycerides are the main storage form of fat in animals and plants.

Hence the correct option is A.

Answers

Answer:

1- substitution.

2- neutral.

Explanation:

The change in the genetic sequence of the organisms known as mutation. Mutations might be sudden and heritable in nature. spontaneous mutation and induced mutation are types of mutation.

A change that causes a change in single base pair of a gene sequence is called substitution mutation. The original leucine sequence is GTT and the mutated sequence is GTG. Thus T has been substituted by G.

Mutation can be beneficial, detrimental or neutral. The neutral mutation is that does not affect the physical change. Both GTT and GTG code for the same amino acid so it would be neutral.

The carrying capacity for a population of frogs in a rainforest ecosystem is 840 frogs, and the maximum rate of increase for this population is 1.0 per individual per year. Using the logistic population growth model, what is the approximate population growth rate for 212 frogs?

4 frogs per year
29 frogs per year
158 frogs per year
314 frogs per year

Answers

Answer:

4 frogs per year is the answer

In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity (K).

Formula used:  dN/dT= rN{1-N/K}

Given: k= 840 frogs

            N= 212, r= 1 year

To find: r=?

Solution:

putting value in equation:

                          dN/dT= rN{1-N/K}

                          dN/dT = 1 x 212 {1-212/840}

                   so,    dN/dT= 158.57 ( approx)

                   

Final answer: The correct option is (c)

158 frogs per year

Thus, we can conclude that 158 frogs per year will be the population of frogs.
