Answer:
D
Explanation:
Alternative energy is best defined as the use of energy sources other than traditional fossil fuels, which are considered environmentally harmful and are in short supply. Fossil fuels consist of natural gas, coal, and oil. Currently, fossil fuels are the most used energy source to heat our homes and power our cars.
Answer:
D.)
Explanation:
Alternative energy is best defined as the use of energy sources other than traditional fossil fuels, which are considered environmental harmful and are in short supply.
How is cell division different in prokaryotes and eukaryotes
Answer:
Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other cell structures. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles.
Explanation:
Answer:
Prokaryotes have fewer cells structures, have no nucleus, and have a singular chromosome. Eukaryotes, however, have multiple chromosomes that contain a nucleus, cell structures, and many organelles.

Which statements describe hormones in plants? Check all that apply.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Hormones help buds form and grow in the winter.
Auxin is the only hormone involved in plant development.
(i know that the first 4 are not right and neither are A, B, and D (1, 2, 4)
Answer:
The correct statements are: 1, 2, and 3.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Explanation:
Plant hormones such as Auxins perform various roles and helps in the growth and development of the plants. Cutting the main stem of the plant stimulates the auxin hormone and which stimulates the lateral elongation growth of the leaf growth.
Some tropisms are controlled by the hormones such as phototropism by auxin as a high concentration area of the auxin causes cell growth in a particular area and the concentration of auxin is stimulated by light.

Based on one of the four scenarios below, create an explanation for how Natural selection works, incorporating all of the 5 concepts that contribute to it.
1. Galapgos Darwin's Finches
2. Caribbean Anoles
3. Giraffe lab
4. In a field that is mostly green because of regular rain, the coat color of the mice species that lives there is mostly dark colors. Over a period of 10 years, there is a drought, and the grass has a lot more dead material, making the field have a much lighter over all color. What happens to the population of mice (coat colors) and why?
5. Make up your own scenario (tell me it) and then describe how natural selection would take place with changes.
Answer:
Population of mice having dark coat colors decreases by changing of features of natural selection.
Explanation:
The population of mice having dark coat colors decreases if the field has light colour due to drought conditions because they are vulnerable to their predators and natural selection. In green field, dark colour mice can't be seen by the predators that will leads to increase their population while on the other hand, if there is drought condition it will leads to increase the population of light colour mice because they can't be seen by predators and decreases the population of dark colour mice due to vulnerability to their predators. Food type availability to the organisms due to environmental conditions lead to natural selection of that organisms which can feed on that food type.

For a circular or square patch of habitat, the ratio of edge habitat to interior habitat __________ as the size of the patch decreases. View Available Hint(s) For a circular or square patch of habitat, the ratio of edge habitat to interior habitat __________ as the size of the patch decreases. decreases increases in square patches and decreases in circular patches increases remains unchanged increases in circular patches and decreases in square patches
Answer:
increases
Explanation:
Habitat is defined as a particular environment where a group of organisms normally lives. Some examples of habitat include, among others, forests, deserts, lakes, grasslands, etc. Moreover, an edge habitat refers to a habitat area that is in contact with another. This part of the habitat has ecological importance because it is used by many species in order to find food, refuge and rest. In the question above, it is expected that a greater number of smaller habitats increase edge habitat surface area when compared to the interior habitat area. The ratio between the edge habitat surface area and total habitat area may have a huge impact on entire ecosystems.
Why can enzymes be used over and over again
Answer:
Enzymes are biological catalysts. They catalyse biochemical reactions. They increase the rate of reaction. They do not chemically react or get utilised in the reaction so enzymes can be used over and over again.
What is meant by natural variation in living things?
1.Different species have different attributes.
2.Different individuals within a species have variation because they may express
different alleles for the same traits.
3.All the possible trait variations of a single population
4.The number of organisms a given area will support.
Answer:
Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).

Explanation:
Cell division is not only for generating copy of DNA . Why ?
Answer:
sorry don't know sorry
Explanation:
ok
Answer: During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two "daughter" cells that inherit the same genetic information. ... Healthy cells can perform DNA replication with almost absolute accuracy most of the time.

What will happen to Earth in the future if we continue to increase greenhouse gas emissions?
Answer:
If we continue to increase greenhouse emissions, more of it will build up in the atmosphere, meaning more of the Sun's infrared radiation will be trapped via the Greenhouse Effect. This will cause the planet to warm.
