succession? Giveanexampleofaneventthat may lead primary
succession.
Answers
Answer:
Primary succession is basically the start of a brand new ecosystem. This is when pioneer species form and grow like lichens and some grasses. Secondary succession is when the ecosystem is already started and it's continuing to grow. During this time populations of other species begin to inhabit the ecosystem like shrubs and trees and some animals. Both of these processes take years to complete. An example of an event would be a volcanic eruption, and a wild fire.

Explanation:
According to Merriam Webster and TheFreeDictionary, the definition of subduct is "A geologic process in which one edge of one crustal plate is forced below the edge of another." Since this sentence indicates that an oceanic plate sinks under the continental plate, therefore I believe the fill-in-the-blank word would be 'subducts' or a similar word.

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.
Answers
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.

the AB blood type is created (mostly) by someone with A blood type making a baby with someone with B blood.
Explanation:
The human blood group is classified into four major classes which are A, B, AB, and O. This is possible due to multiple allelism and codominance which are found in the alleles A and B.
What is blood typing?A blood type is the classification of blood into different groups, based on the presence or absence of antibodies and inherited antigenic substances on the surface of the red blood cells which are present in the blood. These antigens may be proteins, carbohydrates, glycoproteins, or the glycolipids, depending up on the blood group system.
In humans, the blood typing is of four types that is A, B, AB, and O. This is because, the blood typing is an example of multiple allelism and codominance. A and B alleles are codominant and O is recessive.

The theory,of evolution states that all living things had a single common ancestor. The translation between mRNA and amino acids is the same for all living thing. Does the second statement support the theory of evolution ?
Answers
Answer: the theory of evolution states that all living things we can identify descend from the Last Universal Common Ancestor. It is not that the translation process between mRNA and amino acids is universal, but that the underlying genetic code relating DNA nucleotide triplets (codons) to amino acids is the same for almost all living things.
Explanation: The genetic code ‘tells’ mRNA which the sequence of amino acids in a protein and when to stop adding amino acids. The DNA . triplets, called codons, code for 20 amino acids and a STOP signal. The code is identical in almost all cases, but there are variation, mostly found in mitochondrial DNA. But even when these variants exist, most of the code is the same as in other living organisms. For example the codon AGG normally codes for the amino acid serine but in arthropod mitochondria it codes for lysine. These very few and minor changes tend to confirm the single ancestry of the code and how well it has been conserved through billions of replications

Answers
The given question is incomplete as it lack the options, however, answer can be given by the provided information.
Answer:
The correct answer is - 3:1 ratio.
Explanation:
In the question it is given that both male and female both are heterozygous for the trait, let assume dominant allele A and recessive allele a so the the gene for the both male and female is Aa.
Punnett square for the cross between both:
gametes: A, a and A, a.
A a
A AA Aa
a Aa aa
here two out of four are heterozygous dominant and one is dominant and one is recessive.
thus, 3 out of 4 are dominant and one out 4 are recessive.
thus, the answer is 3:1 ratio

Answers
Answer:
Chlorophyll
Explanation:
because they lack roots, stems, and leaves.
The component that can be found in non-vascular plants is chlorophyll. The correct option is C.
What is chlorophyll?Chlorophyll is a pigment that gives plants their distinctive green colour and aids in photosynthesis, which enables plants to produce their own food.
Plants (including algae) can photosynthesize, or use sunshine to change simple molecules into organic compounds.
Chlorophyll makes this possible. The most common kind of chlorophyll found in algae and green plants is chlorophyll a.
Plants lacking a circulatory system made up of xylem and phloem are referred to as non-vascular plants. They may instead have more basic tissues with tailored capabilities for the internal transfer of water.
Mosses, hornworts, and liverworts are examples of nonvascular plants. They don't have leaves, stems, or roots.
Nonvascular plants require a damp environment, are low-growing, and reproduce using spores.
Thus, the correct option is C.

b. increased appetite associated with increased growth rate.
c. increased metabolic rate.
d. increased need for finger foods.
Answers
Answer:
The correct option is A.
decreased appetite associated with decreased growth rate
Explanation:
Feeding problems may develop in preschool age because of decreased appetite associated with decreased growth rate and this is because at the preschool age, there is no rapid growth, the growth rate is reduced which is as a result of decreased appetite for food. We all know that food supply the body with energy and necessary nutrients for growth. When there is decreased appetite enough food needed for growth will not be consumed , hence decrease growth rate.

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.
Answers
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.
The Drosophila genes for white eyes (w), cut wings (ct), and tan body (t) lie at map positions 2.00, 15.0, and 21.0, respectively. Of 1000 progeny, 7 are double crossovers. What is the degree of interference
Answers
Answer:
The coefficient of interference, I, is 0.1 (10% expressed as a percent)
Explanation:
Available data:
genes for white eyes (w), cut wings (ct), and tan body (t) lie at map positions 2.00, 15.0, and 21.0, respectivelyOf 1000 progeny, 7 are double crossovers.The coefficient of interference, I, is complementary with CC.
I = 1 - CC
To calculate the coefficient of coincidence, CC, we must use the next formula:
CC= observed double recombinant frequency/expected double recombinant frequency
Note:
observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.By knowing the positions of genes, we can estimate the distances in MU between them per region.
The distance between w and ct genes is 15 - 2 = 13 MUThe distance between ct and t genes is 21 - 15 = 6 MUNow that we know the distances, we can estimate the recombination frequencies by dividing each distance by 100.
recombination frequency of w-ct region = 13MU / 100 = 0.13recombination frequency of ct-t region = 6MU / 100 = 0.06Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:
EDRF = recombination frequency in region I x recombination frequency in region II.
EDRF = 0.13 x 0.06 = 0.0078
Now, by knowing the total number of individuals in the progeny (1000) and the number of double crossovers (7), we can calculate the observed double recombinant frequency, ODRF:
ODRF = number of double crossovers / total number of individuals
ODRF = 7/1000 = 0.007
Finally, with the values of EDRF and ODRF, we can calculate the coefficient of coincidence, CC.
CC = ODRF/EDRF
CC = 0.007 / 0.0078
CC = 0.9
And by knowing the CC we can also get the coefficient of interference, I.
I = 1 - CC
I = 1 - 0.9
I = 0.1 = 10% (expressed as a percent)
Which of the following is an incorrect match? a. endocytosis – substances taken into the cell b. exocytosis – substances secreted from the cell c. pinocytosis – liquids secreted from the cell d. phagocytosis – large particles taken into the cell
Answers
Answer:
The correct answer is c.pinocytosis – liquids secreted from the cell
Explanation:
Pinocytosis is a type of endocytosis in which substances are internalized into the cell from the celullar exterior. The components are not secreted from the cell but are uptaken into the cell. This internalization process is characterized by the formation of an invagination of the cell membrane where then is formed a vesicle surrounding the component to be uptaken.
