Answer:
c] A red flower and a yellow flower mating to produce an orange flower.
Explanation:
An incomplete dominance in biological terms means a situation where one allele doesn't totally take the expression in a gene, but rather the two parental traits combine to form a secondary trait. As a result of this, a third phenotype comes up, with the physical trait being a mix of the phenotype of the parents.
Therefore, an example of incomplete dominance is a red flower and a yellow flower mating to produce an orange flower.
Answer:D
Explanation:
D is a Orange with orange meaning its incomplete dominance because it both the same theres no other color dominance the other

The change that occurs at point C could be caused by Multiple choice question. A) increased predation by wolves. B) a wet year with increased vegetative growth. C) increased competition from moose herds. D) a dry year with decreased vegetative growth.
Answer:
The answer is "Option B"
Explanation:
A wet season with increased plant growth is indicated by the fact that the population of Elks from beginning point C attained maximum population size (K100) and remained stable until point D. That's why the difference at point C could be due to the a wet year still higher plant growth.

In a certain breed of dog, the alleles B and b determine black and brown coats respectively. However, the allele Q of a gene on a separate chromosome is epistatic to the B and b color alleles resulting in a gray coat (q has no effect on color). If animals of genotype B/b ; Q/q are intercrossed, what phenotypic ratio is expected in the progeny
Answer:
12 gray , 3 black, 1 brown
Explanation:
If Q allele of a gene on a separate chromosomes is epistatic to the B (black) and b (brown) color alleles, in cross between two animals with genotypes BbQq produces 12 gray coat color, 3 black coat color and 1 brown coat color animals.
BbQq x BbQq
Gray coat Gray coat
BQ Bq bQ bq
BQ BBQQ(gray) BBQq(gray) BbQQ(gray) BbQq(gray)
Bq BBQq(gray) BBqq(Black) BbQq(gray) Bbqq(Black)
bQ BbQQ(gray) BbQq(gray) bbQQ(gray) bbQq(gray)
bq BbQq(Gray) Bbqq(Black) bbQq(gray) bbqq(brown)
So the phenotypic ratio is Gray : Black : Brown
= 12 : 3 : 1

Biological organization extends beyond the organism. Which group of terms would be included beyond organism in the same list
Answer:
This question lacks options, the options are:
A. populations, communities, and ecosystems
B. DNA, RNA, and protein
C. Cells, tissues, and organs
The answer is A
Explanation:
The biological level of organization shows the organized build up of life from cellular level to organismal level. However, this organization goes beyond the organismal level. Individual species of organisms can assemble to form a POPULATION.
Likewise, populations of different species can coexist to form a COMMUNITY. The community of organisms can interact with their abiotic environment to form an ECOSYSTEM.
Therefore, the level of biological organization extends as follows:
populations → communities → ecosystems
Put the following steps of Meiosis in the correct order:
I. The cell divides into 2 daughter cells
II. Homologous chromosomes pair up in the center of the cell
III. Spindle fibers separate homologous chromosomes
IV. Chromosomes become shorter and thicker
A. I, II, III, IV
B. IV, III, II, I
C. II, III, I, IV
D. IV, II, III, I
What is Meiosis
Meiosis (listen); from Ancient Greek'lessening', since it is a reductional division) is a special type of cell division of germ cells in reproducing organisms that produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome (haploid). Additionally, before the division, genetic material from the paternal and maternal copies of each chromosome is crossed over, creating new combinations of code on each chromosome. Later on, during fertilization, the haploid cells produced by meiosis between a male and female will fuse to create a cell with two copies of each chromosome again, the zygote.
Errors in meiosis resulting in aneuploidy (an abnormal number of chromosomes) are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities.

What happened to the California Condors?
A. They went extinct in 2002 due to destruction of their habitat.
B. There were only 149 left in the 1980's but even with a captive breeding
program they went extinct in 2010.
C. They went extinct in the 1700's but remains from a well preserved skeleton
contained enough to DNA to begin cloning them.
D. In 1985 there were only 9 left, but a captive breeding program has increased
their number to 300.
Answer:
B
Explanation:
California Condors have been in decline about as long as European Settlements began to spread across North America. These birds have been on the U.S endangered species list since 1967 and were near extinction when their captive-breeding program began. California Condors also mature and reproduce slowly.
he heme prosthetic group consists of protoporphyrin and an iron (II) ion. is the reason for cooperative binding of O2 by hemoglobin. is found only in myoglobin and hemoglobin. is the reason for cooperative binding of O2 by myoglobin.
Answer:
The correct answer is ''consists of protoporphyrin and an iron (II) ion.''
Explanation:
The heme group makes up the prosthetic (non-protein) group of hemoglobin and is responsible for its characteristic red color. It is composed of protoporphyrin IX, in the center of which is the ferrous ion (Fe+2). Protoporphyrin IX, in turn, is composed of four pyrrolic rings. The heme group is synthesized by the mitochondria, where protoporphyrin IX binds with the ferrous ion, before being released into the cytoplasm. The heme group is released in erythrocyte lysis, thus obtaining unconjugated or indirect bilirubin.

Answer:
whats the question then?
Explanation:
Given the enormous heterogeneity of antigen receptors expressed on the populations of naive B and T lymphocytes, the adaptive immune response relies on a process whereby the rare lymphocyte that binds to the antigen is first induced to proliferate, before it can perform its effector function. For B cells, there is a clever mechanism that ensures that the specificity of the antibody secreted by the plasma cell will recognize the same pathogen that initially stimulated the B cell antigen receptor and induced B cell proliferation. This mechanism is:
Answer:
The naïve B cell expresses a membrane-bound form of the antibody as a receptor and secretes that same antibody when it differentiates into a plasma cell.
Explanation:
Naive B cell is a type of B cell that has still not been exposed to the antigen. The B cell receptors (BCRs) are transmembrane proteins composed of 1-a surface immunoglobulin molecule capable of recognizing the antigen, and 2-two transmembrane subunits that transduce the signal. When a B cell binds to antigen with its BCR, the B cell will proliferate and differentiate into a plasma cell. This plasma cell then releases antibodies, which are soluble forms of the BCR where the transmembrane domain that anchors the antibody protein to the membrane of the B cell is eliminated.

The pre-australopith fossils are especially significant because they challenge some of the long-standing explanations of our evolutionary history. Describe two reasons the pre-australopiths force us to rethink the savanna hypothesis in particular. (Hint: Think about the anatomical traits of the pre-australopiths and the environmental and temporal context in which they lived.)
Two important reasons are listed here:
- Pre-australopithecines show evidence of bipedalism but they lived in forested areas
- Ardipithecus ramidus is a human ancestor that lived in a wooded environment approximately 4.2 to 4.5 million years ago
The savanna hypothesis states that early hominid traits were selected in response to increased aridity conditions and the emergence of savanna landscapes (i.e., open grasslands), as forests receded. This hypothesis enables us to understand better the evolution of bipedalism.
Pre-Australopithecines represent the oldest hominids that date from at least 7 to 4.4 million years ago (mya), depending on the species. Pre-australopithecines show evidence of bipedalism (and/or dentition similar to the later hominins who exhibit bipedalism), but it has been shown that they lived in forested areas. Therefore, this observation contradicts the savanna hypothesis which states that bipedalism evolved as an adaptation to the savanna.
Ardipithecus ramidus is a human ancestor dating to between 4.5 and 4.2 mya. The Ardipithecus ramidus fossils were discovered in Ethiopia alongside faunal remains, thereby indicating they lived in a wooded environment. In consequence, Ardipithecus ramidus fossils contradict the open savanna explanation for the origin of bipedalism.

What is gylcosylation
Glycosylation is the reaction in which a carbohydrate, i.e. a glycosyl donor, is attached to a hydroxyl or other functional group of another molecule in order to form a glycoconjugate. In biology, glycosylation usually refers to an enzyme-catalysed reaction, whereas glycation may refer to a non-enzymatic reaction.
Which statement about the genetic code is false?
A. There is no punctuation or spacing between codons.
B. Codons are composed of sets of three nucleotides.
C. Every amino acid is specified by a single codon.
D. The genetic code is almost universal, but not quite.
The statement 'every amino acid is specified by a single codon' about the genetic code is FALSE (Option C).
The genetic code refers to the process by which the heritable information is passed from the DNA sequence to RNA during transcription, and then from RNA to protein during translation.The genetic code is said to be redundant because there are amino acids that can be encoded by more than one codon.For example, the amino acid leucine can be specified by four different codons (CUU, CUC, CUA, and CUG).In conclusion, the statement 'every amino acid is specified by a single codon' about the genetic code is FALSE (Option C).

As you read in this chapter, fungi have long formed symbiotic associations with plants and with algae. How may these two types of associations lead to emergent properties in biological communities
Answer:
Fungi show symbiotic association with algae and plants. With plants, they thrive as endophytes in a form of the symbiotic association. This symbiotic association results in the emergence of novel characteristics in the world of biology.
The lichens function as a tool in finding the quality of air, as they grow in the environment containing good air quality. The tolerance towards heat is another characteristic. Some of the endophytes are witnessed in the plants, which grow in very hot conditions.
At such conditions, no fungi or plant can thrive, however, in the symbiotic association, they possess the tendency to thrive. If one tries to separate them, it results in the death of both.

Answer:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
Plant cells can be larger than animal cells. The normal range for an animal cell varies from 10 to 30 micrometers while that for a plant cell stretches from 10 to 100 micrometers. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
