Which function allows animals to find mates?
movement
homeostasis
reproduction
feeding
Answer: MOVEMENT
Explanation:
Movement
Movement can be described as the change in the place of an object or animals, without the ability to move there is not a possibility of life on earth. Movement is essential for many animals that help them to find food, shelter, and mate for the reproduction and produce offspring by mating.
The function that allows animals to find mates is movement, which is present in the first option as movement is a unique characteristic that is only present in animals but not in plants.
What is the significance of the movement?In the animal kingdom, movement is required to find a mate, as the animal must move from one location to another to find a suitable mate, while it is absent in plants. Plants do not move, but pollinators assist in this process, whereas animals use movement to find food by walking on their legs or flying, and they also use movement to find mating partners.
Hence, the function that allows animals to find mates is movement, which is present in the first option as movement is a unique characteristic that is only present in animals but not in plants.

What are cell cycle regulators
Answer:
Cell cycle regulators are the cell cycle only when they are tight bound to CDKS.
Explanation:
To be fully active, the CDK/Cyclin complex must also be phosphorylated in specific locations. Like all kinases, CDKS are enzymes (kinases) that phosphorylate other proteins. Phosphorylation activates the protein by changing its shape.
How do substances get into and out of the cell?
Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

The pulmonary circulation carries blood between the heart and ______
Answer:
lungs
Explanation:
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
Which of the following is NOT true about matter in the biosphere?
a) Matter is transferred in one direction through the biosphere. b) Biogeochemical cycles transform and reuse molecules. c) The total amount of matter decreases over time. d) Human activity does not affect the movement of matter
Answer:
c) The total amount of matter decreases over time.
Explanation:
The statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).
The biosphere refers to the total of all ecosystems of the Earth.The biosphere can be defined as a closed system in terms of matter because matter does not enter or exit.In the biosphere, the total amount of matter remains constant over time, whereas the total amount of energy decreases over time.This energy is lost in the form of heat when it spreads from the Earth's surface and outward into space.In conclusion, the statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

How Clark Developed Seizures
The following list is not in the correct order. The first three events are numbered correctly. Drag and drop the
remaining events in the order that led to Clark's seizures.
picture above for the order.
Answer:
4. Low blood sodium concentration
5. Net movement of free water into the matrix
6. Increased matrix pressure
7. Abnormal neuron firing rate
8. Seizures
Explanation:
Seizures are defined as the common complication of drug intoxication.
As per the clinical observations for Clark , normal blood and matrix sodium concentration lose sodium ions due to diarrhea. As given too much water causes sodium levels to decrease. Due to lower sodium concentration, the free water move into the matrix and increased matrix pressure. This pressure causes the abnormal neuron firing rate to increase which causes seizures.
Hence, the correct order is:
4. Low blood sodium concentration
5. Net movement of free water into the matrix
6. Increased matrix pressure
7. Abnormal neuron firing rate
8. Seizures

What are types of protein ?Like carbohydrates and fats, Proteins are the macronutrient as it provides the body with energy and is essential to building muscle mass., The protein of body made up of 20 different amino acids.
These amino acids are classified into 2 categories such as Non-Essential Amino Acids produced naturally by the body and Essential Amino Acids (EAAs) not produced naturally by the body, consumed through food or supplementation.
Both animal and plant proteins we consume, Most animal proteins are complete proteins, meaning they have all 9 of the essential amino acids (EAAs) but plant proteins are incomplete proteins , they have at least one missing amino acid.

Which of the following is true regarding enzymes?
A one enzyme can work with any substrate
B they can be used extracellularly
C they are made of only protein
D they are used entirely in the reaction
Answer:
C .they are made of only protein
Enzymes can be used extracellularly. Therefore option B is correct.
Enzymes are biological catalysts that facilitate chemical reactions in living organisms.
While enzymes are highly specific in their action, option A is incorrect because each enzyme typically works with a specific substrate or group of related substrates.
Option C is also incorrect because enzymes can be composed of both protein and non-protein components, such as cofactors or coenzymes.
Finally, option D is incorrect because enzymes are not used up entirely in the reaction but rather can be reused multiple times, making them efficient catalysts.
Therefore option B they can be used extracellularly is correct.

Ima say this in the most easy simplest way possible. Genotype is like the physical make up of an organism. In other terms genotype is the actual genes, the actual alleles. Like PP Pp and pp ( dominant / recessive)
And the phenotype is the physical appearance like the stuff you can actually distinguish a person like curly hair, straight hair, brown eyes, blue eyes, black hair. blond hair. Anyways you get the point.
This is the easiest, simplest way I could put it so I hope it helps.
