B) Osmosis requires cell energy while active transport does not.
C) Neither faciliated diffusion nor osmosis requires cell energy.
D) Diffusion of gases and other small molecules requires no energy on part of the cell.
Answer:
The correct answer would be option B.
Osmosis refers to the passive movement of water down the concentration gradient across a semi-permeable membrane. Thus, it does not require cell energy.
In contrast, active transport requires cell energy as it transports substances across the cell membrane against the concentration gradient, that is, from the region of low concentration to the region of high concentration.
It usually gets energy by ATP hydrolysis.
Examples may include sodium-potassium pump, GLUT transporters in intestinal cells et cetera.
Answer:
The answer is B: Haplorhines have better color vision.
Explanation:
Haplorhines are known as dry-nosed while Strepsirhines are known as wet-nosed. Haplorhines and Strepsirhines are two different kind of primates but they have different characteristics such as variation of the brain size, because Haplorhines have bigger brain than Strepsirhines, Haplorhines do not have the enzyme in charge of producing Vitamin C while Strepsirhines have it. Haplorhines have a more developed vision than Strepsirhines. In this sense, Haplorhines possess a layer called tapetum lacidum which allows them to see at night when the light is low, while Haplorhines do not possess tapetum lacidum but, they have something called fovea, which help the to see during the day and have a vision color which is not a feature of Strepsirhines.
Haplorhines and Strepsirrhines are two main classifications of the Order Primates. Strepsirrhines are the wet-nosed primates, primarily nocturnal with larger olfactory centers. Haplorhines, dry-nosed primates, are often diurnal, rely more on vision and need vitamin C from their diet.
The Order Primates is segregated into two groups: Strepsirrhini (“turned-nosed”) and Haplorhini (“simple-nosed”) primates.
Strepsirrhines, also known as the wet-nosed primates, include prosimians like bush babies and pottos of Africa, the lemurs of Madagascar, and the lorises of Southeast Asia. These primates are primarily nocturnal, have larger olfactory centers in the brain, and tend to be smaller in size with smaller brains compared to anthropoids.
On the other hand, Haplorhines, or dry-nosed primates, include tarsiers and simians (New World monkeys, Old World monkeys, apes, and humans). Typically, Haplorhines are diurnal, rely more on their vision, and lack enzymes to produce vitamin C, thus, needing to get it from their food. Distinctive anatomical traits of strepsirrhines include a grooming claw on their second toe and protruding incisors forming a toothcomb. Haplorhines further diversify into Simiiformes and Tarsiiformes with distinctions being narrow nostrils, non-existent or functional tails, and their habitat.

The Civilian Conservation Corps (CCC), the Works Progress Administration (WPA), and the Social Security Act were all New Deal programs instituted by Franklin Roosevelt.
One New Deal program instituted by Franklin Roosevelt was the Civilian Conservation Corps (CCC). The CCC was established in 1933 and provided employment to young men during the Great Depression. They worked on various conservation and infrastructure projects, such as reforestation, soil erosion control, and building parks.
Another New Deal program was the Works Progress Administration (WPA), which was created in 1935. The WPA focused on providing jobs to the unemployed and improving infrastructure. It funded the construction of public buildings, roads, bridges, and airports, as well as supporting writers, artists, and musicians through its Federal Project Number One.
Additionally, the Social Security Act was another significant New Deal program. It was passed in 1935 and established a system of old-age, survivor, and disability benefits for American workers. The Act also included provisions for unemployment insurance and welfare programs.

It gives explanation or definition of any terms which may be unclear and evidence for any assertions. It also includes references to the sources, examples, data, statistics, illustrations etc....all these make he paragraph the best way to present inferred data.
evaluation of this evidence or data;
B. releases negative ions that create an electrical gradient that all sperm swim toward.
C. releases chemotaxic signals to attract sperm to its location.
D. propels itself toward seminal fluid by calcium-dependent kinesis.
Answer:
C. releases chemotaxic signals to attract sperm to its location.
Explanation:
An oocyte is female gametocyte which is involved in the reproduction. It is produced in ovary during the female gametogenesis. After ovulation, during luteal phase, egg is available to be fertilized by the sperm.
Sperm are attracted toward the eggs by the process of chemotaxis which is by following the gradient of chemical secreted by egg.
Thus, the oocytes in the female body control not only type of sperm they want ot attract, but also time at which they attract them.
Homeostasis is needed for an organism to survive because it keeps its internal environment stable.
It ensures that important physiological factors such as temperature, pH and nutritional levels remain within ideal limits. The stable environment allows for the proper functioning of cells and tissues, supporting metabolism as well as the creation of energy and enzyme activity.
Homeostasis enables organisms to adjust to changes in the external environment, by coordinating responses including temperature control, fluid balance, and hormone release. Many organ systems must work together to keep the body balanced. Without homeostasis, cellular processes would be disturbed and the organism's ability to adjust to environmental changes would be compromised, jeopardizing its ability to survive.
