Is this correct? If not plz help!
Which phrase is associated with asexual reproduction but not sexual
reproduction?
Answer: B. Genetically identical offspring
Explanation:
Asexual reproduction that means the parent organism will split into two organisms, and that there will be no mixing of the DNA, as it is the case in case of the sexual reproduction which mixes up the DNA. Therefore the child and the parent organism will contain exactly the same genetic material.

All animals are multicellular, heterotrophic eukaryotes.
Explanation:
Which of the following information would be most useful in determining whether 2 species are closely related?
A) There leg bones look very similar
B) The age of their bones, determined by carbon dating, is the same
C) The dna sequence found in their bones varies by only a few genes
D) The bones were found in the same layer rock
The most helpful way to determine whether two species are closely related is by comparing the appearance of their leg bones which is called as the Analogous structure. So, the correct option is A.
What is an Analogous structure?In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar but not necessarily in structure.
Example of Analogous structures are an insect's wings and a bird's wings are similar in structure. Although each of these species utilize their wings to fly, the origins of their wings are different.
For the aforementioned example, examining the appearance of two species' leg bones will most accurately reveal whether two species are closely related.
Therefore, the correct option is A.

Which wave interaction is shown by the diagram? o absorption o diffraction o reflection o refraction
Answer:I agree
Explanation:
Diffraction wave interaction is shown by the diagram.
What do you mean by diffraction?Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.
The most common example of diffraction occurs with water waves which bend around a fixed object. Light bends similarly around the edge of an object. The animation shows wave fronts passing through two small openings.
Diffraction results from the interference of an infinite number of waves emitted by a continuous distribution of source points. According to Huygens' principle every point on a wave front of light can be considered to be a secondary source of spherical wavelets.

what are the merit of
indigenous education
Answer:
It was a way to protect, preserve and develop traditional indigenous skills and cultures. Education was a significant step towards empowering indigenous peoples to participate more fully in their communities. It was an indispensable asset to attain freedom and social justice.
Answer:
The core of indigenous education in Africa focused on providing each individual in the community with knowledge, practical skills and attitudes in order to prepare them to for his/her role in the society. It is a holistic system, in which apprenticeship, story telling, proverbs and myths played an important role. Traditional education developed in the ‘learners’ a sense of obligation towards the community and made learners to appreciate the history, language,customs and values of the tribal group, keeping in touch with their heritage, their cultural roots. Western education alienates young Africans from their cultural heritage.

Explain what is diffusion and osmosis? Why are they Important to the cell? Explain one example of active transport in the cell. Write a paragraph (5-7 sentences).
-if you help I really appreciate you!
Answer:
Diffusion and osmosis are both passive transport processes that act to equalize the concentration of a solution. In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. Significance of Diffusion and Osmosis Both diffusion and osmosis are really important as these ensure the equalization of forces inside cells and also inside an organism as a whole by spreading all the necessary chemicals and nutrients from highly concentrated area to the low concentration area inside an organism. The intake of water in plants is an example of osmosis. Diffusion is observed when a drop of food coloring is added to a glass of water, where eventually, the entire water content becomes colored.

Night blindness (n) is a sex-linked recessive trait. A woman who is night blind marries a man who is not night blind. What are the genotypes of both individuals?
Answer:
Genotype of night blind woman - XnXn
Genotype of normal man - XY
Explanation:
Given
Night blindness (n) is a sex-linked recessive trait. Let us say it is X linked recessive
In this case a man with XY genotype having a diseased X allele will be night blind while a woman will have night blindness if both the X allele are diseased . In case if only one X allele is diseased in women then, she will be a carrier of night blindness defect
Genotype of night blind woman - XnXn
Genotype of normal man - XY

Briefly explain the neurophysiological basis (i.e. neuronal/axonal activity, synaptic behaviour) of how the monkey grip procedure
performed about the arms is able to cause a greater stretch reflex response in the leg for the same amount of sensory input when compare to a response without the monkey grip procedure.
The monkey grip procedure involves squeezing an object with one hand while the other arm is passively stretched that causes an increase in the stretch reflex response in the leg muscles of the same side that is being stretched.
What are the neurophysiological basis of the monkey grip procedure?The neurophysiological basis involves the activation of descending pathways from the brain modulating the stretch reflex response. When the grip is initiated, activation of motor areas in the brain increases that send signals down to the spinal cord.
These signals inhibit the interneurons activity that causes stretch reflex response causing a greater response in the leg muscles when they are stretched. The stretch reflex involves the activation of muscle spindles in the spinal chord that inhibit or excite the motor neurons that control the muscle.
The monkey grip procedure increases the excitability of the motor neurons controlling the stretched leg muscles that results in a greater stretch reflex response leading to a more forceful contraction of the leg muscles.
Therefore, the monkey grip procedure involves the complex interactions between descending motor pathways from the brain in the spinal cord that underlie the stretch reflex response.

Which natural resource is renewable?
A. coal
B. wind
C. topsoil
D. oil
Wind is the natural resource which is renewable. Therefore, option (B) is correct.
Wind energy is considered a renewable resource because it comes from the natural flow of air masses caused by the sun and the Earth's rotation. Wind turbines turn the kinetic energy of the wind into power, and as long as there is wind, this process can keep going forever.
Wind doesn't run out like coal and oil (options A and D), which are both solid fuels. Topsoil (choice C) is an important resource for agriculture, but it can be worn down or eroded over time, making it non-renewable in the short run if it is not managed well.

An abiotic factor is a part of an ecosytem, but it is not alive. Some examples include water, rocks, sunlight, and the atmosphere.
On the other hand, a biotic factor is a living part of an ecosystem. Some examples are animals, plants, and fungi.
Let's look at the answer choices.
A creosote plant (choice A) kangaroo rat (choice C) and coyote (choice D) are all living organisms. Therefore, they must be biotic factors.
However, rocky desert soil (choice B) is not living. It's a part of the ecosystem, but since it's not alive it must be abiotic.

Which of the following represents an agricultural factor greatly decreasing the availability of crops?
Answer:
Climate.
Explanation:
Climate is the factor which is responsible for the decreasing the availability of crops because climate is the factor that allows crops to grow in the region. Suitable climatic conditions allows us to grow more plants in the region while on the other hand, less or no crops can be cultivated in the harsh climatic conditions. The plants in the harsh climatic condition are unable to grow such as desert where the temperature is very high and no rainfall occurs to support growing of crops.
