Answers
Answer:
Population change is governed by the balance between birth rates and death rates. If the birth rate stays the same and the death rate decreases, then population numbers will grow. If the birth rate increases and the death rate stays the same, then population will also grow
Explanation:
Natural increase in a population occurs where Birth rate is greater than death rate. ... Natural decrease occurs when death rate is greater than birth rate. This means that more deaths occur in a population than babies are born so population numbers decline
The population will be doubled by immigration. The correct option is C.
What is immigration?When an animal settles down in a habitat because it has resources nearby or because it is a good fit for them, this is referred to as immigration.
When an animal emigrates, it's because its habitat is no longer perfect for it and it needs to move to a new location with a better habitat.
It is the quantity of members of the same species that have entered the habitat during the time period under examination from outside the habitat.
To immigrate means to move permanently to another country. To migrate is to move, much like wintertime birds. Depending on the viewpoint, one can either migrate, immigrate, or emigrate.
Immigration can increase the size of a population if the birth and death rates are equal.
Thus, the correct option is C.

In one or two sentences, explain how cats and dogs, both mammals, could be classified as distinct animals. What characteristics set them apart from one another?
Answers
Answer:
Cats and dogs are both mammals because they have hair, are warm-blooded, and nourish their young with milk. Dogs and cats are distinct species, incapable of producing offspring together because of the many differences in their genome.
Explanation:
i hope this was helpful!
Mammals are warm-blooded vertebrate(backbone) animal distinguished by hair or fur on their body.
Mammals give birth to younger ones.Female mammals produce milk in their mammary gland to feed the younger ones.Examples of mammals includes, Huma being, lion, dog, tiger, cat, horse, goat, cow etc.
Since, cats and dogs are both mammals, the difference between them is the genome.Genome is the complete genetic information (DNA or RNA) of an organism.Cats and dogs have different genetic information.

A researcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol. She feeds one group of laboratory rats a daily diet of precisely 125.6 units of niacin and 5,400 units of retinol. She uses two types of commercial pellet food. Food A contains 0.86 units of niacin and 30 units of retinol per gram. Food B contains 0.66 units of niacin and 40 units of retinol per gram. How many grams of each food does she feed this group of rats each day
Answers
Answer:
- 100 grams of food A (x)
- 60 grams of food B (y)
Explanation:
According to this question, the group of laboratory rats are being fed a daily diet of:
- 125.6 units of niacin and 5,400 units of retinol
Let x represent the number of grams needed for food A.
Let y represent the number of grams needed for food B.
This means that:
Food A: Niacin = 0.86x, Retinol = 30x
Food B: Niacin = 0.66y, Retinol = 40y
Since there are 125.6 units of niacin fed to the rats in total, then;
0.86x (A) + 0.66y (B) = 125.6
Since there are 5400 units of retinol fed to the rats in total, then;
30x (A) + 40y (B) = 5400
Solving these two equations simultaneously using elimination method:
0.86x (A) + 0.66y (B) = 125.6 ........(eqn 1)
30x (A) + 40y (B) = 5400 ............ (eqn 2)
Multiply eqn 1 by 30 and eqn 2 by 0.86
30 × 0.86x + 0.66y = 125.6
0.86 × 30x + 40y = 5400
25.8x + 19.8y = 3768 ............ (eqn 3)
25.8x + 34.4y = 4644 ........... (eqn 4)
Subtract eqn 3 from eqn 4
14.6y = 876
Divide both sides by 14.6
y = 876/14.6
y = 60
Substitute value for y (60) into eqn 2
30x + 40y = 5400
30x + 40(60) = 5400
30x + 2400 = 5400
30x = 5400 - 2400
30x = 3000
x = 3000/30
x = 100
Therefore, she feeds the group of rats 100grams of food A (x) and 60 grams of food B (y).

Answer:
1. Hypothalamus
2. Optic chiasma
3. Corpora quadrigemina
4. Cerebellum
5. Thalamus
6. Medulla oblangata
7. Corpus Collosum
8. Fornix
9. Cerebral aqueduct
10. Midbrain
Explanation:
The hypothalamus is a small central region of the brain that regulates body temperature by responding to both internal and external stimuli and also produces the antidiuretic hormone (ADH) in order to trigger the reabsorption of water in the kidneys. The optic chiasma is a special sensory structure located along the visual pathway, directly in front of the hypothalamus, which is crucial to vision. The corpora quadrigemina, also known as quadruple bodies, are reflex centers located in the mesencephalon (midbrain) that regulate the position of the head and eyes in response to somatic stimuli. The cerebellum is a part of the brain located behind the top part of the brain stem which is involved in motor movement regulation and balance control. The thalamus (massa intermedia) is a paired gray matter structure found near the center of the brain that plays vital roles associated with sensory and motor functions of the brain. The medulla oblangata (medulla) is a structure located at the base of the brain involved in the regulation of sensory, motor, and mental functions (e.g., breathing, pain modulation, etc). The corpus callosum (the callosal commissure) is a bundle of nerve fibers that connects the two hemispheres of the brain. The fornix (agenesis of the corpus callosum) is a large interhemispheric commissure that connects neurons in the right and left hemispheres. The cerebral aqueduct (aqueduct of Sylvius) is a narrow channel that connects the third and fourth ventricles, thus allowing the cerebrospinal fluid to flow between the ventricles. Finally, the midbrain o 'mesencephalon' is a small region located in between the forebrain and hindbrain, which is involved in auditory and visual processing, eye movement and coordination.

how proteins are made
Answers
Proteins are an important class of molecules that carry out most of the work inside cells. The building blocks of proteins are smaller organic molecules called amino acids. Most organisms, including humans, use only 20 different amino acids to assemble the vast multitude of proteins needed to build and run a cell.
To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
After the polypeptide chain is synthesized, it will sometimes undergo additional processing. For example, some proteins will have certain amino acids removed. Or extra molecules such as sugars or phosphates may be attached to some of the amino acids in a protein.
Answer:
proteins are made of large numbers of amino acids joined end to end. The chains fold up to form 3d molecules with complex shapes - you could think of it as origami with very long and thin piece of paper
