What is the function of; 1.plumule,
2.embryo,
3.hilum,
4.microphone
5.and cotyledon?
Answer:
1=Function of Plumule (shoot tip): The plumule is the part of the embryo that develops into the shoot bearing the leaves of the plant. The plumule gives rise to aerial shoots. The function of cotyledon: They store reserve food material or serve as photosynthetic organs in young seedlings.
2=An embryo is the early stage of development of a multicellular organism. In general, in organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization and continues through the formation of body structures, such as tissues and organs.
3=. In botany, a hilum (pronounced /ˈhaɪləm/) is a scar or mark left on a seed coat by the former attachment to the ovary wall or to the funiculus (which in turn attaches to the ovary wall). ... The adjectival form hilar denotes the presence of such a mark, and can be used as a distinguishing characteristic of a seed or spore........!!!!!
4=A microphone is the device responsible for transferring sound as it travels through the air, and converting it into electrical impulses that can be amplified by PA systems, or recorded by either analog or digital recorders.
5= Cotyledons help supply the nutrition a plant embryo needs to germinate and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.

explain the sugar translocation in the plant starting with the leaf cell
(source cell) to the root cell (sink cell).
Answer: I think this is it.. Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The photosynthates from the source are usually translocated to the nearest sink through the phloem sieve tube elements.

What is the volume of 2.7 moles of N2 at STP?
Answer:
60.48L
Explanation:
By definition, at STP (Standard Temperature and Pressure), any gas takes up a volume of 22.4L.
Consequently, because the ideal gas law (PV=nRT) states that the number of moles is directly proportional to the volume of the gas, 2.7M of N2 takes up a volume of:
2.7*22.4L
=60.48L

A classmate tells you that the good thing about renewable resources like trees is that you can use them and use them and they will never run out. What is your classmate misunderstanding about renewable resources?
A renewable resource has been different from the nonrenewable one by the fact that the renewable resource is replenished faster than it is used.
What is a Renewable resource?A renewable resource could be defined as a type of resource that significantly continues to exist in nature despite being consumed or can replenish itself over a period of time even as they are utilized by the organisms.
A classmate tells you that the good thing about renewable resources like trees is that you can use them and use them and they will never run out. Renewable resources may include wind power, solar energy, geothermal energy, biomass, etc. These resources are available in nature in unlimited amounts as compared to non-renewable resources.
Therefore, a renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used.

Explanation:
Los jugos gástricos presentes en el estómago tienen un pH de aproximadamente1.87 ¿Cuál es la concentración de iones H+ presentes en los jugos gástricos?
Answer:
1,35 * 10 ^ -2 M
Explanation:
Recuerde que pH = -log [H ^ +]
Sea la concentración de iones de hidrógeno [H ^ +]
Si es así, entonces;
-pH = log [H ^ +]
Por lo tanto;
[H ^ +] = Antilog (-pH)
[H ^ +] = Antilog (-1,87)
[H ^ +] = 1,35 * 10 ^ -2 M
A group of marine scientists introduced a species of fish into an artificial habitat and wanted to determine if it will grow well in the new environment. They recorded the population over several years and their data is plotted below. Analyze the data and formulate a conclusion. Does this species of fish do well in this habitat? Predict what will happen to the population over the next five years.
Answer: The graph appears to show an exponential growth among the school of fish. This is good for their species, because the artificial habitat suits their needs. The next five years would probably continue to grow this way if the environment doesn't change too rapidly.
Most people develop wisdom teeth by early adulthood. Wisdom teeth can cause pain or crowd out their other teeth, so many people have these teeth removed. Wisdom teeth in modern humans do not perform a crucial life function.
Which statement best describes the importance of wisdom teeth to human evolution?
A. They are vestigial structures that once performed an important function for human ancestors.
B.They are evidence that humans have never evolved.
C. They are vestigial structures that never performed a necessary function for human
ancestors.
D.They are evidence that humans cannot evolve.
Answer:
A
Explanation:
There's a reason they grew there in the first place. The Caveman mouth was much larger than our modern mouths.
The statement that best describes the importance of wisdom teeth to human evolution is that they are vestigial structures that performs function for human ancestors.
What do you mean by Evolution?Evolution may be defined as the change in the characteristics of a species over several generations and relies on the process of natural selection.
Wisdom teeth are evolved in humans because early humans needed to chew coarse, hearty foods, they required a broader jaw. Wisdom teeth grew in to give them more chewing power for this purpose.
Therefore, the statement that best describes the importance of wisdom teeth to human evolution is that they are vestigial structures that performs function for human ancestors.

Answer:
island biogeography
Explanation:
I hope this helps.
Investigation of ecological relationships and distribution of species and isolated communities is known as "island biogeography".
What is island biogeography?A subfield of biogeography called island or insular biogeography studies the variables that influence the species diversity and richness of isolated natural groups. The theory was initially developed to explicate the species-area relationship trend found in oceanic islands.
What is ecological relationships?Ecological balance being described as "a condition of dynamic equilibrium within such a community of animals in which genetic, species, including ecosystem diversity, remain largely stable, subject to progressive changes during natural succession" by a number of online dictionaries. "A consistent equilibrium in the populations of each species"

What would happen to a population if all females reproduce through parthenogenesis alone?
Answer:
All the offspring from parthenogenesis are female. So if the female stick insects carry on reproducing alone, the males could be wiped out. ... This may help explain why parthenogenesis remains rare, even in species that are capable of it. In such species, "males typically force females to mate".

To model ocean water in different places on Earth, a student pours equal amounts of water in two containers. He adds the same amount of salt to each container and stirs until the salt is completely dissolved. He places Container 1 in a cool place in the house and Container 2 outside in the sunlight. After two hours, he tests the salinity of water in each container. What should the student MOST LIKELY conclude, and why?
Answer:
The correct answer would be - container 2 will have less salinity than container 1.
Explanation:
The given experiment can give an idea about how the temperature of surroundings can affect the salinity, volume, and density of the water that has the same amount of water and salt dissolved in it. The independent variable or the only variable that is different is their place that has a difference in the temperature. Container 1 is placed in a cool place while container 2 is placed in sunlight.
We know that the warmer the water it takes more space so, therefore, less density. Density and salinity both have a positive relationship so an increase in density increases the salinity and vice versa. Thus, here the salinity of container 2 would be low in comparison to container 1

Process of change by which descendants come to differ from their ancestors
A. Evolution
B. Natural Selection
C. Phenotype
D. Variation
Natural selection causes changes in? A.genotypes. B.populations. C.individuals. D.phenotypes.
Answer:
populations
Explanation:
A) genotypes
Natural selection may happen because of different genotypes (for example, heterozygous individuals survive better). Natural selection does not change genotype.
Recall that genotype is the type of alleles one has.
B) populations
Natural selection is the survival of the fittest. For example, a drought. Or predators. Or limited food supply. Or overproduction. All will end up with the stronger, better-surviving types of a certain population. Natural selection does change populations.
C) individuals
Natural selection usually occurs when there are large amounts of a certain type of individual (for example, bunnies). They usually do not affect individuals.
D) phenotypes
Natural selection may happen because of different phenotypes (for example, green grasshoppers survive better than red ones). Natural selection does not change phenotype.
Recall that phenotype is the physical appearance one has.
Extra:
Phenotype vs. Genotype:
If A is dominant for brown hair and a is recessive for albino hair:
Genotype Aa has a phenotype of brown hair.
Genotype AA has the phenotype of brown hair.
Genotype aa has the phenotype of albino hair.
You can see how genotype and phenotype are like.
Natural selection causes changes in populations. The correct option is B.
What is natural selection?Natural selection is a biological mechanism that allows some organisms to survive and reproduce more successfully than others, resulting in the transfer of advantageous traits from one generation to the next.
Natural selection operates on the and phenotype genotype of the organism. It causes changes in the frequency of genes (genotype) in a population, which results in changes in the physical appearance (phenotype) of the population.
A population is a group of individuals of the same species living in the same geographical area at the same time. Natural selection affects populations, not individuals, as it occurs over several generations, and it results in changes in the allele frequencies in the population. Thus, natural selection causes changes in populations.
Therefore, the correct option is B.
