what is the final step in the water cycle?
Answer:
The funny thing is that the water that falls from the sky as rain today, might have fallen last week, last month, last year or thousands of years ago. It is the greatest recycler of all time! There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection.

Explanation:
Rabbits in most areas have a brown coat. The arctic hare has a bright white coat in
winter. How does the arctic hare's white color help it survive?
Answer:
Indeed, rabbits, in most of the planet, tend to have their fur colored brown, copper or other similar shades. Now, in the Arctic regions, these animals do not have this color, but a white one, similar to the environment that surrounds them. This is so because these animals, for evolutionary reasons, have adapted their fur to the snowy environment that surrounds them in the Arctic, in order to avoid being detected by potential predators, protecting themselves and trying to ensure their survival.
The original base sequence of DNA is : CAG TTA CCA. If the amino acid sequence that results from translation of this DNA base sequence is: valine-tyrosine-glycine, what mutation occurred in the DNA? Explain
A. An addition mutation occurred
B. A deletion mutation occurred
C. A substitution mutation occurred
D. A mutation did not occur.
C
I think substitution, because the original translation of the original base sequence is glutamine-leucine-proline. The base sequence for valine-tyrosine-glycine is: GT# TA# GG# . of course the last codon is unclear, but the first two gives us enough to know too much change happened for a simple addition or deletion mutation. The bases were completely switched out, therefore it is a substitution mutation. I attached a codon chart.
At the end of Meiosis II, each daughter cell has 23 single-stranded chromosomes.
True
OR
False
Answer:
y the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. ... Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
Explanation:
30 chromosomes
Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.
From a diploid germ cell 2n =24 double stranded chromosomes, meiosis will produce four gamete haploid cells n =12 single stranded chromosomes.
Meiosis produces four with half because double stranded chromosomes represents DNA replication. Twice as much DNA as a diploid cell needs.
From a diploid germ cell 2n =24 double stranded chromosomes, mitosis will produce two diploid daughter cells 2n =24 single stranded chromosomes for the same reason.
DNA replication doubles the genome before cell division. Sister chromatids of double stranded chromosomes represent the replicated DNA. During cell division, sister chromatids of double stranded chromosomes are separated into different cells.
Meiosis has two stages, the first separating homologous pairs of double stranded chromosomes, and then the second stage separating sister chromatids into four haploid (n) gametes.

_________.
At the organism level, ________.

embryonic development.
Answer:
Hi your answers would be transcription factors, TATA boxes, and homeotic genes
Eukaryotic gene regulation takes place through the use of RNA- binding proteins called transcription factors and short regions of DNA that help position RNA polymerase called TATA boxes.
At the organism level, homeotic genes control the differentiation and development of cells during embryonic development.
Transcription factor:Transcription factors are proteins involved in the process of converting, or transcribing, DNA into RNA. Transcription factors include a wide number of proteins, excluding RNA polymerase, that initiate and regulate the transcription of genes. Regulation of transcription is the most common form of gene control.

Tundra
Explanation:

True. The statement "In terms of plant life, this biome is extremely high in diversity, but there are very few animals that live here" accurately describes a tropical rainforest biome.
What is tropical rainforest biome?Tropical rainforest biome is known for its high level of plant biodiversity and relatively low number of animal species compared to other biomes. Tropical rainforests are home to a wide variety of plant species, including trees, shrubs, and epiphytes, but the dense vegetation and high rainfall make it difficult for many animal species to establish themselves.
However, the few species that are able to survive in the rainforest typically have specialized adaptations that allow them to thrive in this unique environment.

Organs are composed of cells that are composed of subunits called tissues.
Organs are composed of tissues that are composed of subunits called cells.
Answer:
Organs are composed of tissues that are composed of subunits called cells.
Explanation:
In biology, there are five levels of organization that makes up living organisms. These five levels of organization make up one another in the following ascending hierarchical order:
Cell → Tissue → Organ → System → Organism
Based on this hierarchy, cells make up tissues, tissues make up organs, organs make up systems, and systems make up an organism. According to this question, the most accurate description of the levels of biological organization in the option is "Organs are composed of tissues that are composed of subunits called cells".

Rainforests are habitats for many plants and animals. However, habitat fragmentation is occurring because of human activity. When a rainforest is fragmented, a large area is divided into small patches that are isolated from each other. Species living in these patches are more likely to become extinct as a result of overcrowding and competition.
Which of the following is the best way to minimize the effects of habitat fragmentation on the biodiversity of a rainforest ecosystem?
A.
constructing boundaries and fences around each habitat patch
B.
building natural green pathways across the original habitat to join all the patches together
C.
building concrete roads across the original habitat to join all of the patches together
D.
introducing new species that compete with the existing species in each habitat patch
Building natural green pathways across the original habitat to join all the patches together. Option B
What is rain forest?A rainforest is characterized by towering, largely evergreen trees and heavy rainfall. Some rainforests have existed in their current form for at least 70 million years, making them the oldest existing ecosystems on Earth.
Hence we can see that the best way to minimize the effects of habitat fragmentation on the biodiversity of a rainforest ecosystem is building natural green pathways across the original habitat to join all the patches together.

__________ give you energy and help you feel satisfied after eating.
Animals, including humans, derive chemical energy from their food to support their metabolism, including their muscular activity.
What is the source of energy from food?The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.
Cells release energy from nutrients through the process of respiration. The majority of the time, glucose has already been produced from the food.
Because they work quickly and provide energy as soon as they are taken, carbohydrates—which have 4 kcal per gram—are the foods that are used as an energy source the most frequently.
