from his monohybrid crosses, Mendel developed his first law
Answer:
Im confused but if your asking for Medel's first law it would be states that for the pair of alleles an individual has of some gene (or at some genetic locus), one is a copy of a randomly chosen one in the father of the individual, and the other if a copy of a randomly chosen one in the mother, and that a randomly chosen one will be copied

Answer: 10 years
Explanation:
When the student is not able to pay the loan on regular basis then the repayment plan is available that is called standard repayment plan. It is a kind of default plan for all and most kind of student loans. In this the monthly payment is broken down of an amount of $50 which is the minimum amount for loan pay for the duration of maximum 10 years. This payment plan helps to lower down the interest money on the payments.

A geneticist crossed pure breeding black mice with pure breeding brown mice. All the mice in the F1 generation had black coats. When these mice were crossed, they yielded 961 black coated mice and 317 brown coated mice.
Fill in the new combinations of alleles in the F2 generation.
Answer:
The correct answer is - the brown allele is not independent from the black allele and disappears in the F1 generation.
Explanation:
IN this question it is given that there is a cross between pure black and pure brown breed and the F1 generation has all-black coat offspring and their self cross produced 961 black and 317 brown.
The black coat offspring is three times than the brown coat offspring in F2 generation which means they have 3:1 ratio that comes in the self cross of heterozygous only there for the F1 generation black coat offspring have the heterozygous genotype for the trait,
Thus, the brown allele is not independent of the black allele and disappears in the F1 generation.

Explanation:
What is the independent variable?
What is the dependent variable?
Answer:
the independent is the age of the tree and the dependent is the diameter
Explanation:
the diamter of the tree is based off of the age as we can see that it gets bigger the older the tree is
Answer: Independent variable: age of the tree (years), Dependent variable: tree diameter (mm)
The diameter of the tree is dependent on what age the tree is. As the tree gets older, the diameter increases. The dependent variable depends/relies on the value(s) of the independent variable.
Mistletoe extracts water and nutrients from the spruce to the spruce tree's detriment. What relationship is shown here between the mistletoe and the tree?
A.Competition
B.Parasitism
C.Mutualism
D.Commensalism
Mistletoe extracts water and nutrients from the spruce, to the spruce tree's detriment. The relationship that is shown here between the mistletoe and the tree is Parasitism. Hence, the correct option is B.
What is Parasitism?Parasitism refers to a type of symbiotic relationship in which one organism benefits at the expense of the other organism, which is called host. The parasite lives on or inside the host and derive nutrients as well as shelter from the host, thereby providing no benefit to the host in return.
Examples of parasites includes tapeworms, roundworms, lice, fleas, and some species of bacteria and viruses.
Parasitism is a common for of symbiosis in nature and play an important role in shaping the relationships between species and maintaining balance in ecosystem. Hence, the correct option is B.

18. How has the use of herbicides affected agricultural productivity?
O A. Fewer crops are organic because of the use of Bt toxin.
B. Fewer pesticides are needed because of parasitoids.
O C. Fewer people are needed to weed because of herbicides.
D. Fewer crops are produced because of herbicides.
Answer:
B. Fewer pesticides are needed because of parasitoids.
Explanation:
Herbicides are chemicals utilized to manage or command unwanted vegetation. Herbicide employment happens most commonly in row-crop cultivation, where they are employed before or throughout seeding to maximize yield productivity by decreasing other vegetation. Yields have improved considerably, and, in association with tillage, herbicide use decreases erosion, fuel usage, greenhouse gas discharges, and nutrient run-off, and preserves water.
why would an athlete need to be concerned about a twitch or sustained contraction
Answer:
why an athlete would need to be concerned about twitches or contractions is because, whenever they perform, and such thing happens, it will most likely distract the athlete, and cause the athlete doing his/her performance to not be as good, and may lead to failure, for example, when someone is running very fast for a sprinting race, and he has a contraction in his leg it will cause him to react by showing signs of pain by slowing down or even tripping and falling, causing him to lose the race.

1. Construct an Explanation Based only on the information provided, why could the
mRNA section be translated into three different sets of amino acids, instead of just one
set?
2. Use Models Use the genetic code to translate the sequence into each of the three
possible sets of amino acids.
3. Draw Conclusions Which of the three sets of amino acids is the most likely to be
included in the polypeptide? Explain your reasoning.
Answer: three sets: ile. leu,phe,cys,leu,glu. glu,ile,cys,leu,val,asp,leu
The most likely sequence to be included is the R to L read, because of the STOP codon if read L to R. The lone ile would be the last amino acid of a different polypeptide, and there is no promoter sequence after the STOP codon.
Explanation:
auu,uaa,cug,uuc,ugu,cua,gag
Ile,STOP,leu,phe,cys,leu,glu
glu,ile,cys,leu,val,asp,leu (reverse)
After a STOP codon, a DNA promoter is required
Codons are the trinucleotide sequence found in the DNA and RNA. These codons code for specific amino acids and describe the relationship between the nitrogenous bases of the DNA.
1. Codon is the set of three nucleotides, in which amino acids can be coded by different codons.
In the given sequence, the mRNA can translate the sequence into more than one set as the sequence must contain a promoter and a stop codon.
2. In the given set, the possible amino acid sequences can be given as:
Glutamic acid, isoleucine, cysteine, leucine, valine, aspartate, leucine
Isoleucine, Ochre, Leucine, Phenylalanine, Cysteine, Leucine, Glutamic acid
3. The codon sequence, which has a promotor sequence after a stop or start codon will have more chances to be translated during the process.
In the given sequence:
Isoleucine, Ochre, Leucine, Phenylalanine, Cysteine, Leucine, Glutamic acid
The polypeptide will be stopped due to the presence of a stop codon in the polypeptide.

(Choice B)
B
The sex of sea turtle offspring depends on the incubation temperature.
(Choice C)
C
The largest number of male sea turtles will develop at 28
(Choice D)
D
Most of the sea turtle eggs hatched if incubated at 26
Answer:
Choice B i had this question a long time ago ;)
Explanation:
Answer:
The sex of sea turtle offspring depends on the incubation temperature.
Explanation:
1.) In low incubation temperatures (26°C) and high incubation temperatures (36°C), a large number of sea turtle embryos die.
2.) In temperatures 30°C and below, no males hatch, and in temperatures 34°C and above, no females hatch. This suggests that the sex of the hatchlings is affected by incubation temperature.
3.) The correct answer is: The sex of sea turtle offspring depends on the incubation temperature.

Explanation:
The net ATP gain at this stage of cellular respiration is 36. Therefore, option "D" is correct.
What is cellular respiration?A series of chemical reactions known as cellular respiration breaks down glucose into ATP, which can be used as energy to power numerous body processes. Cellular respiration has three main stages: the citric acid cycle, glycolysis, and oxidative phosphorylation.
In eukaryotes, the 4 phases of cell breath incorporate glycolysis, progress response (pyruvate oxidation), the Krebs cycle (otherwise called the citrus extract cycle), and oxidative phosphorylation through the electron transport chain.
Therefore, cellular respiration is the main process that generates ATP and gives energy to the body to work.

The pathophysiology of osteomalacia involves a. collagen breakdown in the bone matrix. b. inadequate mineralization in the osteoid. c. crowding of cells in the osteoid. d. increased osteoclast activity.
Answer:
The correct answer is - b. inadequate mineralization in the osteoid.
Explanation:
Osteomalacia is a condition where the bones become weak and soft, this bone softening is occurred due to mainly vitamin D deficiency that also causes rickets. It leads to insufficient or inadequate mineralization in the osteoid.
This conditing when takes place in kids and young adult leads to curve or bowing during the growth period. In this case, bones are very prone or easily fractured.
