Answer:
The correct answer is : The dominant form of the trait shows.
Explanation:
In simple dominance, the attribute related to the prevailing or dominant allele is communicated while the character related to the latent or recessive allele is persecuted or masked. For instance –
Taking a bloom where the dominant allele attribute is red shading and the recessive allele characteristic is white shading. At the point when a posterity of this bloom is created containing one prevailing or dominant allele and one passive allele, its shade would be red simply because just the predominant allele communicates its characteristic.
Thus, the right answer is: The dominant form of the trait shows.
At the molecular level, gene duplication often produces novelty in a lineage. This process provides another evolutionary pathway by which a protein can switch functions, without loss of the original function. What analytical approach helped the most to answer the question of evolution in the aldosterone-M receptor pair in the study of Jamie Bridgham and her colleagues
Answer:
Bridgham et al. (2006) showed that the interaction between a steroid hormone (aldosterone-M) and its receptor (mineralocorticoid) evolved by Darwinian gradualism. In this work, the authors demonstrated a primitive affinity between the hormone and its receptor that was initially present in chemically similar but more ancient ligands. This result has implications in understanding the association between gene duplication and the evolution of hormone signaling pathways. For example, in invertebrates, this work reinforces the importance of gene duplication in the existing interaction between paralogous glucocorticoid receptors and their receptor mineralocorticoid genes that were derived from duplication (Thornton 2001).

How are meiosis and mitosis different?
O A. Mitosis has anaphases I and II, but meiosis has only anaphase I.
O B. Meiosis produces four cells, but mitosis produces two cells.
O C. Chromatids are formed only during the process of meiosis.
O D. Mitosis produces haploid cells and meiosis produces diploid cells.
Answer:
B
Explanation:
Meiosis and mitosis are different, as meiosis produces four cells, but mitosis produces two cells that are present in Option B, as mitosis produces two genetically identical daughter cells, while meiosis produces four genetically diverse daughter cells.
What are meiosis and mitosis?Mitosis is a process of cell division that occurs in somatic (non-reproductive) cells, where a single cell divides into two identical daughter cells. The purpose of mitosis is for the growth, repair, and replacement of cells in the body, whereas meiosis is a type of cell division that occurs in reproductive cells (germ cells) and is involved in the production of gametes (sperm and egg cells) in animals. Meiosis involves two rounds of cell division, known as meiosis I and meiosis II, and makes the gametes.
Hence, meiosis and mitosis are different, as meiosis produces four cells, but mitosis produces two cells that are present in option B.

PLEASE HELP!! In a population, the number of organisms hovers around 10 per acre. When the number goes much higher, the organisms cannot find enough food, and some don't survive. When it goes much below, they thrive and reproduce quickly. What is the limiting factor in this example? *
Answer:
food and land
Explanation:
A limiting factor is the one that limits the growth of any organism’s population. Here the population growth of an organism is limited by both availability of food and land. As the population grows, the food availability gets limited and hence most of the organism die.
But when the population reduces, the food quantity becomes surplus and thus the organisms survive.
Answer: Food and land
Explanation:
That is what it is a limiting factor of because they dont have the neccesary food and land

In order for the muscle fatigue to end the muscle cells must be provided with
Answer:
oxygen
Explanation:
Everything needs oxygen, even your cells because oxygen is crucial in process of ATP production which basically powers all of our actions. Hence, when you cells have low O2 your muscles will tire out quickly due to lack of energy thus you need to replenish them with Oxygen so that you can put an end to fatigue.
Review the equations used to describe photosynthesis and respiration (as provided in the introduction and background section of this experiment). Why was it important to use germinated seeds without leaves for this experiment?
Answer:
1. Photosynthesis equation: 6CO2 + 6H2O + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Respiration equation : C6H12O6 + 6O2 --> 6CO2 + H2O + ATP
2. Provided that the seeds had leaves the response between the NaOH and the CO2 would be destroyed by the leaves which would change the oxygen levels in the test tube or cylinder.
Explanation:
Photosynthesis and respiration both are the essential parts of the carbon cycle in atmosphere. Photosynthesis use carbon dioxide from the atmosphere while respiration releases carbon dioxide back in to atmosphere. CO2 is the major component that helps in carbon recycle in carbon cycle.
In this experiment it is required to use the germinated seeds without leaves because seeds with the leaves will disrupt the reaction of NaOH and carbon dioxide that will lead to inaccurate oxygen level in the experiment tube.
Thus, the correct answer is :
1. Photosynthesis equation: 6CO2 + 6H2O + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Respiration equation : C6H12O6 + 6O2 --> 6CO2 + H2O + ATP
2. Provided that the seeds had leaves the response between the NaOH and the CO2 would be destroyed by the leaves which would change the oxygen levels in the test tube or cylinder.

is it a good idea to sterilized thins that are to be sent to the moon
Answer:
Yes, it is a good idea to send the objects on the moon after sanitization or after sterlization so that it not causes harm in any way.
There is a bit different type of environment on the moon and the objects must not be sent as it is on the way.
The objects has to be sterlized so that it does not reacts entering into the moon's environment.
The objects sent on the moon are usually metals and other reactive or non reactive materials that can affect the people carrying the objects, spaceship or via any other means.
So, its better to send sterlized things into the space so that it cannot harm anyone.

Explanation:
_________14. In photorespiration, carbondioxide is produced in the _________ when glycine is converted to serine.
A. Peroxisome B. Lysosome C. Mitochondria D. Chloroplast
Answer:
Option D, chloroplast
Explanation:
The process of photorespiration starts in the chloroplast when oxygen attaches to the RuBP. This produces three compounds namely – a) Three carbon compound (3-PGA) and b) Two carbon compound (phosphoglycolate). 3-PGA act as an intermediate to the Calvin cycle and before entering this cycle two of its carbon are removed. To recover lost carbon, plants taken in carbon through series of reactions involving phosphoglycolate. One fourth of the total carbon transported through this pathway is released as CO2. Since this entire process takes place in chloroplast, it can be said that CO2 is produced in chloroplast
Hence, option D is correct

What best describes the Frank-Starling law?
a. The Frank-Starling law states that the slower the heart rate, the greater the cardiac output.
b. The Frank-Starling law states that the greater the volume of blood discharged from the heart, the greater the pressure required to discharge the blood.
c. The Frank-Starling law states that the greater the stroke volume, the greater the heart rate.
d. The Frank-Starling law states that the more the ventricular muscle cells are stretched, the more forcefully they contract.
Answer:The Frank-Starling law states that the greater the volume of blood discharged from the heart, the greater the pressure required to discharge the blood
Basically, the FSL states that the greater the stroke volume of the left ventricle will increase, as the volume of the the ventricles increases due to ventricular contraction, leading to systolic contraction.
If the volume of the blood in the Ventricle is increased, the blood volume stretches the ventricular walls and the ventricle contracts.The amount of blood ejected from the ventricle increased(stoke volume).Therefore, the higher the contraction of the ventricles, Myocyte stretch, the more the volume of blood in the ventricle pushed, and the more the amount of the blood ejected from the ventricle as Stroke Volume.

Explanation:
When crossing these two heterozygous parents, you will get the phenotype 3:1. This means...
75% chance of plant being tall
25% chance of plant being short
Since T is dominant and we are using simple Mendelian inheritance, the heterozygous offspring (Tt) will be tall as well.
This means there is a 25% or 1/4 chance of the plant being short.

They provide more niches for animals to live in.
They do not have natural predators to regulate their population growth
They cause the climate in an area to become cooler.
They provide food resources to native organisms.
They compete with native organisms for resources.
Previous Activity
The correct answers are B. They do not have natural predators to regulate their population growth and E. They compete with native organisms for resources.
Explanation:
Nonnative species include any species that does not belong to an ecosystem but was introduced to it. Nonnative species are considered are an important threat to biodiversity and native species because they usually disrupt the natural equilibrium in the ecosystem.
This usually occurs because nonnative species population grow rapidly due to the lack of natural predators; for example, Asian carps which are native from Asia and were taken to the U.S. are eaten by other fish and animals in their native ecosystem, but once they are introduced in another ecosystem their population increases due to lack of predators. Additionally, nonnative species often compete with native species for resources, this also happens with the Asian carp that competes for food such as snails or mussels with native species in the U.S.

Categorize each relationship as mutualism or parasitism
The question is unclear, is there more to it?
I cannot answer this question without knowing the circumstances, but it is good to remember that mutualism is where both species and/or participants benefit, and parasitism is where one species benefits and the other one is harmed.
Think of mutualism like the word mutual, so when people say " the feeling is mutual" it means that both parties feel and/or express the same feelings. Parasitism should be thought of like a parasite. When one is infected or has contracted a parasite, the parasite will live off of its host body making it ill or even causing death as it drains resources from its host to benefit itself.
Suppose you are involved in a project studying a population of Dalea purpurea (purple prairie clover), a diploid, bee pollinated plant growing at Cayler Prairie in NW Iowa. You collect a sample from 100 individuals and assay DNA sequence variation at the apetala locus, which controls floral morphology. You find two distinct sequences: L and S. Individuals that are LL have very large petals, LS plants have medium sized petals, and SS plants have small petals. Your sample of plants yields the following observed and Hardy-Weinberg expected (HWE) genotypic counts:.Genotype: Observed Counts: HWE Counts:LL 14 9LS 32 42SS 54 49a. The population is in Hardy-Weinberg equilibrium, giving no indication of the preferences of the bees.b. LS heterozygotes are favored due to hybrid vigor.c. Bees are preferentially visiting smaller flowers resulting in a reproductive advantage for plants with smaller petals.d. LL genotype plants have a reproductive advantage due to their larger flowers.e. Bees preferentially cross-pollinate flowers of the same size (like size mating with like) resulting in inbreeding with respect to genotypes at the apetala locus.
Answer:
Option E
Explanation:
Bees preferentially cross-pollinate flowers of the same size (like size mating with like) resulting in inbreeding with respect to genotypes at the apetala locus.
Inbreeding increases the frequency of homozygousity and deviates from the assumptions of the hardy Weinberg's principle
