Answers
Answer:
represses gene transcription and promotes mRNA translation.
Explanation:
Homeotic gene refers to any group of genes that controls the pattern of formation of body structure during early embryonic development of organisms. These genes encode proteins which is called transcription factors that direct cells to form various parts of the body. Homeotic genes is the master control genes that regulate other groups of genes that are responsible for the development of body parts that will develop in different locations.

Use your codon chart to determine the amino acid sequence. Remember to read through the strand and ONLY start on AUG and STOP when you reach a stop codon (UGA, UAA, or UAG). Follow the example in the box. Abbreviate the proteins using the first three letters of the amino acid name.
Answers
Methionine (AUG)Amino acids can be abbreviated using the first three letters of their name.
Methionine can be abbreviated as Met.
The given RNA sequence is AUGUAACGAUGCGUCGUGGCAUCAUGCUGCGUCAGCGGCGAGUCUGACCCGUCUCUAACAGGACGGCCGGGCGUUGUCGUUGA.
We can use the codon chart to determine the amino acid sequence.
The codon chart is used to determine which amino acid is coded by a particular codon in a strand of DNA/RNA.A codon is a sequence of three nucleotides in DNA or RNA that encodes for a specific amino acid.
Each codon codes for a different amino acid.
For example, the codon AUG codes for the amino acid methionine.
To determine the amino acid sequence, we start reading the RNA strand from the start codon AUG and continue reading until we reach a stop codon (UGA, UAA, or UAG).
Then we write down the amino acid sequence for the codons we read, using the codon chart.
Here, the sequence starts with AUG, which codes for methionine.
After that, the next codon is UAA which is a stop codon, so we can stop.
The amino acid sequence is therefore Methionine. So, the answer would be Methionine (Met).

8) The logistic growth function f(t)=320/1+7.0e^-.27t
describes the population of a species of butterflies t months
after they are introduced to a non-threatening habitat. How many butterflies were initially introduced to the
habitat?
Answers
A population in biology is a collection of organisms belonging to the same species that coexist and interact in the same habitat. A population might consist of plants, animals, or microbes and can range in size from a few to millions of individuals.
We must utilize the logistic growth function to solve for the starting population (P0) of butterflies with t=0 in order to determine the initial population of butterflies.
\(f(t) = 320/1 + 7.0e^(^-^0^.^2^7^t^)\)
When t=0,
\(f(0) = 320/1 + 7.0e^(^-^0^.^2^7^*^0)\\f(0) = 320/1 + 7.0e^(^0^)\\f(0) = 320/1 + 7.0(1)\\f(0) = 320 + 7.0 f(0) = 327\)
Therefore, 327 butterflies were the initial population transferred to the area.

What else is missing from this equation that a plant needs in order to do photosynthesis?
Answers
A plant needs carbon dioxide and light energy in order to perform photosynthesis.
Commonly used equation for photosynthesis is: \(6CO_{2}\) + \(6H_{2}O\) → \(C_{6}H_{12}O_{6}\) + \(6O_{2}\). This illustrates how light energy is absorbed by chlorophyll (implied by the arrow) to turn the reactants, six carbon dioxide molecules and six water molecules, into a sugar molecule and six oxygen molecules, the products.
Photosynthesis is a process by which the plants use light energy and carbon dioxide from the atmosphere to convert into glucose sugar and oxygen. Oxygen is required by every living organism to respire and live. Whereas, glucose produced is used by plants as their food constituent and is generally stored in the form of starch.

the number of chromosomes in each cell is the

2. Independent assortment
3. Crossing over
Explanation:
Meiosis is a kind of cell division that reduces the chromosome number of the parent cell by half. It only occurs during sexual reproduction and ensures genetic variation in sexually reproducing organisms.
Meiosis contributes to genetic variability when the chromosomes line up randomly at the cell plate during METAPHASE 1 of meiosis. This process of random alignment is called INDEPENDENT ASSORTMENT of genes. Generally, meiosis is able to ensure genetic variability due to a process called CROSSING OVER. Crossing over is a process whereby nonsister chromatids of homologous chromosomes exchanges/shuffles genetic contents.

Answer:
No
Why not:
The midpoint of range is 3000. Yes, in from 1950-1955 there was a massive increase of the population of chipmunks but from then on it slowly decreased until 1990. In 1995, the population doubled from 1990. If you double 1440, you will get 2880. The biologist said between 2900-3100, using the midpoint of this range (3000) it is too low therefore being a bit unreasonable.

Answers
Chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell.
However, the length of meiosis varies greatly even across species lacking developmental holds. For instance, in animals, it varies from 1-2 days for male Drosophila melanogaster and over 24 days for males of various Orthopterans and Homo sapiens. Half of the original 46 chromosomes, or 23 chromosomes, will be present in each daughter cell. There are two sister chromatids on each chromosome. The daughter cells now enter meiosis II, the third and last stage of meiosis. Two haploid cells are present at the conclusion of meiosis I.A chromosome has a tetrad (4 chromatids or 4 DNA molecules) during prophase I and metaphase I of meiosis, which is then reduced to two chromatids (2 DNA molecules) by the time metaphase II takes place.

Starting with the European settlers, humans have introduced earthworms from Europe and Asia into North American forests. These introductions continue through the transport of soil that contains non-native earthworms, such as during construction and through the release of non-native earthworms used for fishing. The effects of non-native earthworms are especially large in forests that did not have any native earthworms. For example, forests of the Great Lakes region did not previously have earthworms until humans introduced them. When non-native earthworms are introduced, the thick layer of leaves, known as leaf litter, covering the ground disappears quickly, thereby altering biogeochemical cycles.
What is a possible negative consequence of introducing the non-native earthworms to forests in the Great Lake regions?
PLease hurry
The earthworms reduce the resources available to other animals that eat dead plant matter.
