Answer:
An autotroph makes its own energy and a heterotroph gets its energy from eating other organisms.
Explanation:
Autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Heterotrophs cannot make their own food so they must eat or absorb.
how long will take an object traveling at 25 m/s to reach a distance of 125 meters?
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
What's the connection between pace and distance?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.

someone pls help with this
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.
what nutrients supply your body with energy?
Answer:
protein, carbohydrates, and fat
Answer:
Carbohydrates, protien and fats
Explanation:
Three main nutrients used for energy are carbohydrates, protein, and fats, with carbohydrates being the most important source. Your body can also use protein and fats for energy when carbs have been depleted. When you eat, your body breaks down nutrients into smaller components and absorbs them to use as fuel.

Enzymes always have a specific shape.
B
Enzymes are destroyed after they are used.
С
Enzymes are composed of amino acid chains.
D
Enzymes temporarily associate with a reactant.
Answer: I think it’s B???
Explanation: Ok maybe it’s B. during the Kreb’s cycle and stuff similar to that, after the enzyme is used, I believe it is produced as a byproduct? You don’t have to use this is you don’t want to. Please do not use it if you are not sure. Sorry....

Which Punnett square represents a cross between two parents that are heterozygous for purple flowers?
Answer:
The allies for the purple color of the flowers of pea
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.

In the food chain of "algae-------> mosquito larvae --------> frogs -------> racoons," algae are the Consumers Heterotrophs Detrivores Autotrophs
Answer:
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.

Which element matters least in the process of natural selection?
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.

Analyze the model of the cell membrane below. Which of the following statements is true about the phospholipid components of the cell membrane? Both components of the phospholipids are hydrophobic. Both components of the phospholipids are hydrophilic. The tails are hydrophilic while the heads are hydrophobic. The tails are hydrophobic while the heads are hydrophilic.
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.
