Explanation:
Can someone answer this please.
Answer:
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.The first true primates evolved by 55 million years ago or a bit earlier, near the beginning of the Eocene Epoch. Their fossils have been found in North America, Europe, and Asia. They looked different from the primates today.

Which feature increases the absorption of glucose in the small intestine
Answer:
The correct answer is villi.
Explanation:
The carbohydrates consumed by human beings are further dissociated into its mono forms, that is, fructose, glucose, and galactose. Of these monosaccharides, about 80% is glucose, which gets absorbed with the assistance of absorptive cells in the small intestine. In the walls of the small intestine, the food after digestion is passed into the blood vessels via the process of diffusion.
The mucosa or the inner wall of the small intestine is enveloped by finger-like tissues known as villi that further comprise microscopic finger-like outcrops called microvilli. These villi and microvilli enhances absorption of nutrients as they increase the surface area of the small intestine. Thus, the absorption of glucose within the small intestine is enhanced by the presence of villi.
How does the urban and natural water cycle compare?
Answer:
Explanation:
he natural water cycle is a continuing process of evaporation, condensation, precipitation and groundwater (Figure 1). ... The urban water cycle (Figure 2) shows the consequences of increased development. More development and more concrete means less infiltration of rainwater into the soil, and more run off.
~Hope it helps! And stay safe~
Both the urban and natural water cycles have a lot of differences in their properties and occurrence. This is because due to the presence of artificial surroundings in urban areas.
What do you mean by the water cycle?The water cycle may be defined as the continuous movement of water throughout the atmosphere. It involves all the processes and stages of water.
Due to the development in the urban areas, the natural water cycle gets affected. The natural water cycle deals with evaporation, condensation, sublimation, etc. but the urban water cycle has concrete walls, infertile soil, and a ruptured environment where there is less or no rainfall at all.
Therefore, Both the urban and natural water cycles have a lot of differences in their properties and occurrence.

Devegetation affected a number of nutrient reservoirs and processes in the experimental watershed. Note that the rate of decomposition was not affected by devegetation because the decomposers were not affected by the treatments and because the plant remains contributed plenty of organic nutrients to the soil to sustain decomposition for the duration of the experiment. Drag the labels to indicate the change in the size of the reservoir or the change in the rate of the process as a result of devegetation. Labels may be used once, more than once, or not at all.
Answer:
Devegetation affect the nutrient reservoir and watershed due to not using of nutrient and increases soil erosion.
Explanation:
Devegetation refers to no vegetation on a piece of land. If there is no vegetation present on land, the nutrient reservoir remain full because no plant is available for the absorption of nutrients from the reservoir. Devegetation also affect water quality of watershed. Erosion is the main problem of those areas where there is no vegetation and the upper layer of soil is washed by the rainfall.

1. In Japanese four o'clock flowers, color is inherited by genes that show incomplete dominance. In such flowers, a cross between a homozygous red flower and a homozygous white flower will always result in pink flowers.
Answer:
Explanation:
Incomplete dominance occur when two allele expresses itself in the phenotype of an organism.
Its a situation where by an allele is not dominant over another other in an heterozygous condition but it gives a blend of the two allele in the phenotype of the offspring.
Example is the phenotype of a 4'o clock plant that gives pink flower when a red flower is crossed with white flower.

Explanation:
Paige turns on an electric space heater in the center of her bedroom. The coils glow, and the room becomes warmer. How is heat reaching the corners of Paige's bedroom?
Think of it this way. Osmosis occurs when water flows to a different side given its a membrane or not. This is because it flows to a less dense area to reach equilibrium between the two sides. Heat is very similar. It will try to spread to places where there is not as much heat. Keeping the laws of heat travels up, the heat from the coils will reach the ends. We call this "Thermal Equilibrium"

List three particles found in blood plasma and give their main purpose.
Answer:
Blood plasma is a 'yellowish liquid' component of blood that holds the blood cells in whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume. It is the intravascular fluid part of extracellular fluid. It is mostly water, and contains important dissolved proteins, glucose, clotting factors, electrolytes, hormones, carbon dioxide, and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood disorders.

Up to this point, did you notice any differences between the development of male and
female gametes?
Explain
Both male and female gametes are produced by different organs and in different sizes.
The main difference between male and female gametes is that male gametes which are known as sperm cells are produced in large numbers by the male reproductive organs whereas female gametes are called egg cells which are produced single at a time by the female reproductive organs.
Both male and female gametes are formed by meiosis type cell division. The female gamete is a large in size and motile while the male gamete is small in size and also motile so we can conclude that both gametes are produced by different organs, numbers and sizes.

Is there a connection between intensity of UV radiation and skin color?
Answer:
Explanation:
Sun exposure which also includes its intensity is responsible for detrimental damage to the skin ranging from sunburn, etc and skin cancer.They also aid in the accumulation of DNA lesions which are unable to be repaired by the body systems which are distributed throughout the whole epidermal layers and the uppermost dermal cells in light, intermediate and tanned skin while they were restricted to suprabasal epidermal layers in brown or dark skin in interaction with the individual's genetics.
To solve this problem of damage to the skin, a way to do this was to evolve skin that was dark to protect against the sun's more damaging rays. Melanin, the skin's brown pigment, is a natural sunscreen that protects tropical peoples from the many harmful effects of ultraviolet (UV) rays as the sun rays is a lot high in these areas.
This type of reproduction in plants is centered around the flower's ovum
and pollen fusing together:
Answer:
sexual reproduction
Explanation:
The type of reproduction in which the ovum and the pollen of a flower fuse together is refer to as sexual reproduction.
The ovum of a flower is equivalent to the female reproductive part while the pollen is equivalent to the male's reproductive part. During fertilization, the female reproductive part (the ovum) fuses with the male's reproductive part (the pollen) to produce a zygote.
how does a scientist answer a scientific question?
Describe what the observations imply about how starlings are affected by flocking behavior in the wild and explain how evidence suggests that flocking behavior provides an advantage to starlings.
Answer:
Explanation:
Starling is a bird from the family sturnidea. It originated from Europes and Asia from where it introduced to other part of the world. They lives in the wild.
Starling birds moves in group or tight flock from a place the other. They usually form a flock called murmuration where they move together in group following each other to avoid predation.
Starling have been able to survive on the wild with this behaviour. They stir above the average height of their neighbor in a coordinated manner preventing them from being caught by preys.
