Explanation:
What can be a recessive or dominat??
Answer: There are many examples of recessive traits in non-human animals as well. In dogs, traits like yellow fur, white spots, and smooth hair are recessive. In cats, white fur, brown (as opposed to black) fur, and long hair are recessive traits. In sheep, black wool and blue eyes are recessive.
Also Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

-What genotypes would the parents have to be to have a child with hemophilia?
Answer:
If the father has hemophilia and the mother DOESN'T the daughters any will have and the sons won't. If the moms have it and the dad doesn't that means all of the sons will have it and the daughters won't
Explanation:
Mark as Brainliest
Answer:
Male/Dad: XhY
Female/Mom: XHXh
Explanation:
Hemophilia is a sex-linked recessive disorder. Due to this, this means that the genotypes of those affected would be:
XhXh (female)XhY (male)Doing a quick punnet square using XhY x XHxH would equal to 25% XHXH (unaffected female), 25% XHXh (female carrier), 25% XHY (unaffected male), 25% XhY (affected male).
Correct me if I'm wrong, please!
How does geography influence climate?
Answer:
Geography affects the weather in many ways. ... Topographical features like mountains affect the weather mostly in the way that they direct air currents. For example, air is forced to rise over mountains. Moist air will cool as it rises, and then the clouds release the water, causing precipitation like rain or snow.

Which shape has four equal side lengths? (2 points) a a quadrilateral with one small square in each of the four corners, and single arrows going in the same direction for one pair of the opposite sides and double arrows for the other pair of opposite sides b a quadrilateral with double arrows going in the same direction for one pair of the opposite sides c a quadrilateral with sides of different lengths d a quadrilateral with a short line on each side
Answer:
D. a quadrilateral with a short line on each side
Explanation:
This question is describing a SQUARE, which is a quadrilateral with four sides equal. A square has four angles as well, which are of equal sizes as well i.e. 90% each.
A quadrilateral with one small square in each of the four corners showing that each angle is a right angle (90°). In a square, same line are on each side showing that any side with the short line has the same length, hence, all sides have an equal length.

Explanation:
SOMEONE PLEASE HELP Which of the following examples is MOST likely to result in the formation of a new species? Select one:
A
A farmer applies a new fertilizer to her crops in order to encourage a much greater yield of corn.
B
An invasive species is introduced into the sea when an oil tanker releases the water it uses to float near a coral reef.
C
Many trees are knocked down when a new road is paved through a forest where many animal species live.
D
A fish population is divided when a long drought causes a lake to separate into two smaller bodies of water,
Answer: D
Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species could lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.
A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.
D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.

2 paragraphs about Ecosystems: What is an ecosystem?
Answer:
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscapes, work together to form a bubble of life.
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.

A cell is the basic unit of structure and function in living organisms. What would you call an organism made up of many cells?
Answer:
Multicellular organism, an organism composed of many cells, which are to varying degrees integrated and independent.
Explanation:
A researcher has a laboratory strain of flies that have loss-of-function mutations in both gene X and white. These flies are used as hosts for P element transformation: Embryos of the double mutant strain are injected with two plasmids, one containing a wild-type copy of the white gene (w+) and a wild-type copy of gene X, side-by-side within P element inverted repeats, and the other plasmid containing only the P element transposase gene. Transgenic offspring of the injected flies will
Select one:
a. have both plasmids integrated randomly into the genome.
b. have white eyes and express transposase.
c. have red eyes and a wild-type copy of gene X in place of the mutant copy in their genome.
d. have red eyes and a wild-type copy of gene X integrated into a random location in the genome.
Answer:
d. have red eyes and a wild-type copy of gene X integrated into a random location in the genome.
Explanation:
P elements are genetic mobile elements, i.e., transposons, which are highly mobile in the Drosophila germline. These transposons naturally cause a high rate of mutation in Drosophila germline cells resulted from an interstrain cross of males with autonomous P elements and females without P elements, a phenomenon known as hybrid dysgenesis. Moreover, a transposase in an enzyme required for the mechanism of transposition (in this case, to mediate the transposition of P elements which are reinserted randomly). The P elements have provided a useful mutagenesis system widely used in molecular biology and genetics research. In fly transformation, it is required to use plasmids with a P element (P plasmids) which contains a w+ (red-eye) marker and recognition sequences for the transposase. In this case, the embryos injected with P plasmids will contain all the components to insert the reporter gene (red-eye marker) and the wild-type copy of gene X into a random site of the genome.
Before cellular division, the cell must duplicate its DNA so that the daughter cells will contain complete copies of the dna. Which characteristic of DNA makes it most suitable as a molecule for this role?
A. DNA is located in the nucleus
B. DNA is a large macromolecule
C. DNA is made of repeating sugar-phosphate subunits
D. DNA is made of two strands of complementary nucleotides
Answer:
D. DNA is made of two strands of complementary nucleotides
Explanation:
As rightly stated in this question, DNA replication must occur prior to cell division because each daughter cells must receive an equal and correct amount of genetic material (DNA). DNA replication is the process by which the DNA molecule duplicates to form two identical copies of itself.
This replication characteristics of DNA is achievable because "DNA is made of two strands of complementary nucleotides". The double-stranded DNA first unwinds into two single strands. After which, each single strand serves as a template for the new DNA strand. Two strands of a DNA molecule are complementary to one another.

how does reducing gene flow cause speciation
Answer:
reduction of gene flow can occur due to geographical isolation too
or it can be dur to sympatric or allopatric speciation an occur.
where due to this the species are being behaviouraly isolated, and mad too reject mating due to certain reasons. Moreover mutations too can take palace causing for a genetic drift. Where the isolated species may undergo selection pressure too. So as an overall view the gene flow eventually decreases since the species diversity along with the genetic diversity decreases causing fare the reduction of the gene pool.
After many generations a new species will be formed. Resulting for speciation.

how does a bryophyte excrete?
Answer:
They do not excrete
Explanation:
Bryophytes have neither pollen nor flowers and rely on water to carry the male sperm to the female eggs. The spore capsules are produced after a male gamete (the sperm) has fertilized a female gamete (the egg). Hence the spores are part of the sexual reproductive cycle.
Answer:
Bryophytes excrete with the help of erect stem with spirally arranged leaf like structures and with rhizoids (hair like structures that function as roots) at the base.

Many countries in Europe and Africa are reluctant to import Genetically Modified Organisms (GMO) produced foods from the United States because Question 33 options: they could severely alter local agricultural economies. they could possibly crossbreed with domestic varieties they would cause economic dependence on US corporations. they are considered less nutritious. all of the above.
Answer:
The correct answer is - all of the above.
Explanation:
GMO or genetically modified organisms are organisms that are genetically engineered to alter their genetic material, DNA, in order to increase or improve the quality of the organism. The products are produced by these organisms are produced are known as GMO foods or products.
Such products have many reasons that these products are banned to many countries and many countries in Europe or Africa. The major reasons are-
These foods lead to local agriculture economy as there would be better food products in less price, these products will increase the dependency on the USA for such products. Many consider these products are less nutritious.
