Can you help me with the question listed in the pictures below? Please and thank you. Will mark BRAINLIEST!!! :)

Answer:

a) x4        b) Eyepiece x10 Objective x40

Explanation:

a) x4 magnification

The 4x objective lens has the lowest power and, therefore the highest field of view. As a result, it is easier to locate the specimen on the slide than if you start with a higher power objective.

b)

Eyepiece Lens: the lens at the top of the microscope that you look through. The eyepiece is usually 5x, 10x or 15x power.

Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers.

To get 400 we need to use a combination that, multiplied together, will give us 400.

If the eyepiece lens is 10x then 400/10 = 40

So if we use the 10x Eyepiece lens with the 40x Objective Lens we will get a total magnification of x400.

Answer:

5 sec

Explanation:

125m

25 m/s

= 5 sec

It will take 5 seconds for an object traveling at 25 m/s to reach a distance of 125 meters.

Speed = distance / time

Time = distance / speed

Distance = 125m

Speed = 25 m/s

Time = 125 / 25 s

Time = 5 s

The rate is the time fee of exchange of the distance. If 'D' is the distance of an item in some time 'T', the rate is the same too, s = D/T. It has equal devices as speed.

Velocity, being a scalar amount, is the fee at which an object covers distance. The average speed is the distance (a scalar amount) according to the time ratio.

Explanation:

Punnett square is a square diagram which is used to predict the genotype of the offspring produced by particular cross.

Let P and p be the alleles of the gene responsible for the flower colors in a plant.

The genotype of both the parents is given as heterozygous that is, Pp.

Two types of gametes would be formed P and p.

Autotrophs

Explanation:

Food chain is a step by step feeding process in an ecosystem where an organism producer is been feed on by another organism that depends on it

called consumer and it is also feed on by predator. Producer usually produce their food its includes plants, Algae, phytoplankton.

The energy level moved from the producer to the last organism on the chain.

Autotrophs are the same as producer and an Algae food chain is an example of aquatic food chain where algae serves as primary source of energy(Producer) and its been feed upon by mosquito larvea and larvea by frogs and frogs are eaten by racoon.

Answer:

It would change the way they gain energy by the animals not having enough things in the body to get it functioning right.

Explanation:

think of it as gas our cars need gas to run, so do animals and us but our gas is food

If animal cells had chloroplasts, it means animals would be able to gain energy directly from sunlight by being able to manufacture carbohydrates as a food source.

The presence of chloroplast would allow an animal cell to photosynthesize and manufacture foods in the form of carbohydrates.

[tex]6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2[/tex]

The food can be broken down during respiration in order for the energy to be extracted.

[tex]C_6H_1_2O_6 + 6O_2 ---> 6CO_2 + 6H_2O[/tex]

This would be in addition to animals' ability to gain energy from external food sources through the same respiration.

Answer:

Bar graphs are used to compare separate items.

Explanation:

A bar graph is used because it helps to compare items. So the correct option is A.

Bar graphs are a kind of pictorial representation of data which is generally in grouped form. It can present the data in the form of both vertical and horizontal rectangular bars.

In this graph, the length of the bars is used as proportionate to the value of data. These graphs are also called bar charts. Bar graphs are one of the various methods of data handling in the field of statistics.

Statistics is defined as the collection, presentation, organisation, analysis, and interpretation of data observations. In statistics, there are various other methods of data representation. These are tables, bar graphs, pie charts, histograms, frequency polygons, etc.

A bar graph is one of the several methods of data representation and is used for comparing the values of items in the data.

Therefore the correct option is A.

Given question is incomplete as it lacks the group of choices. However, the group of choices associated with the question is as follows:

1. Organisms must display variation.

2. A trait must increase reproduction.

3. A trait must directly affect metabolism.

4. A trait must increase survival.

5. A trait must be able to be passed on to future generations.

Answer:

The correct answer is : option 3. A trait must directly affect metabolism.

Explanation:

The process that leads to change or adaption in the species or a population of the organism known as natural selection. In this process population exhibits the variation in the population due to the change or adaption.

This variation refers to the better traits and increased reproductive ability, suited to the environment than others which is also known as survival of the fittest as they increase their survival in comparison to the other population or species. Natural selection carries traits that are passed on to one generation to another.

Thus, the correct answer is option Is : 3. A trait must directly affect metabolism.

Answer:

This question appears incomplete but The correct option is the last option

Explanation:

Cell membranes are made up of a lipid/phospholipid bilayer in which each layer consists of an hydrophilic head (water loving) and a hydrophobic tail (water fearing). The hydrophobic tail of each layer is oriented inward and the hydrophilic heads are oriented outward so the cell can interact with water molecules inside (the cytoplasm) and outside the cell environment. This orientation forms a critical part of the function of the cell membrane that makes it a selectively permeable barrier that regulates what goes in and out of the cell.
