The DNA of prokaryotes is not enclosed within a membrane, and is instead localized to a region called the nucleoid. This DNA acts as the prokaryote’s only chromosome, so the process of DNA replication is much quicker. After DNA replication, the original chromosome and its copy seperate. A cleavage furrow forms between the cell, the cell eventually pinches in half, and two identical daughter cells, each with an identical chromosome, are formed.
What are the 4 reasons that natural selection occurs?
Answer:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

Why is this statement true or false?
True; specific body parts will develop from specific cells or groups of cells in an embryo.
False; any cell in a mature embryo can develop into any cell of the body.
False; specific body parts do not develop from specific cells or groups of cells in an embryo.
True; all cells in a mature embryo can develop into muscle.
Answer:
True; all cells in a mature embryo can develop into muscle.
Explanation:
True; all cells in a mature embryo can develop into muscle. Therefore, the mesoderm in an embryo will become the organism’s muscles.
What develops from mesoderm?The middle layer of the three germ layers, the mesoderm, forms during gastrulation in the very first stages of most animals' embryonic development. The ectoderm is the outer layer while the endoderm is the inner layer. mesoderm-derived tissues.
All other body tissues, such as the dermis of the skin, the heart, the muscular system, the urogenital system, the bones, and the bone marrow, are formed from mesoderm cells, which are found between the endoderm and the ectoderm (and therefore the blood). In this process of organogenesis, which is the formation of organs, the mesoderm interacts with the endoderm and the ectoderm to give rise to the organs.

English. Noun. The layer of the Earth's atmosphere directly above the mesosphere and directly below the exosphere.
Answer:
thermosphere is thermosphere (layer of the earth's atmosphere) while troposphere is troposphere.
ation:
This layer also contains ratios of nitrogen and oxygen similar to the troposphere, except the concentrations are 1000 times less and there is little water vapor there, so the air is too thin for weather to occur. The thermosphere is the uppermost layer of the atmosphere.

The correct option is "J" which shows the position of the Sun, Earth and Moon have the greatest effect on ocean tides.
What positions of the sun the moon and earth have the greatest effect on ocean tides?Both the Moon and the Sun affect the ocean waves, the Moon plays the biggest role. Although the Sun's gravitational pull on the Earth is 178 times more robust than the Moon's, the tidal bulges it causes are much smaller.

How do individuals in a population get their traits?
Answer:
New traits can also come from transfer of genes between populations, as in migration, or between species, in horizontal gene transfer. Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift.

Explain your observations on what organisms need to grow. Explain how human activity can impact an organism’s ability to obtain the resources it needs to survive. State your opinion about how human activity can be changed to have less impact on the lives of other organisms.
Answer:
All living organisms need food, water, and shelter in order to grow and survive. Human activities can have a lot of impacts on different organisms; whether they’re good or bad. Humans may take away natural habitats for some by expanding into a previously untouched area. In the same sense, they might end up accidentally providing a food or water source. Although there is some good, humans should limit and change their activities in order to have a less impact on the lives of other organisms. We could create more national or state parks, which would make a safe haven for a lot of organisms. We could impose stricter punishments for people for litter as it harms organisms. We might create nature preserves in order to force humans to leave alone the other organisms in a certain area. Overall, we play a big role in a lot of different organisms lives and we need to make sure it’s a positive one.
Hope this helped, all written by me so no plagiarism(:
Explanation:
Human activity is a major threat to the planet's biodiversity. This is because human population growth thus far has been exponential, meaning that its growth rate stays the same regardless of population size. This makes the population grow faster and faster as it gets larger.
Populations may grow exponentially for some period, but they ultimately reach a carrying capacity when they become limited by resource availability. Humans, however, have continued to work around carrying capacity as they develop new technologies to help support the ever-growing population. This threatens biodiversity because the more humans there are, the more this displaces other species and reduces species richness. Human-mediated causes of biodiversity loss. Deforestation for resource mining or urbanization can displace native organisms. Deforestation for resource mining or urbanization can displace native organisms.
How are internal and external fertilization alike and different?
Answer:
Internal fertilization is the process when the syn-gamy "union of male and female gamete", occurs inside the female body after insemination using copulation. External fertilization is the syn-gamy outside the female body, that is in the outer environment especially in water bodies. Sorry if this is a late answer.
