Most angiosperms incorporate the assistance of animals in their reproductive cycle. This is a major advancement that gave them an advantage over other plant lineages and helped them become the dominant type of plant on Earth today. Which of the following steps in the reproduction of angiosperms do animals assist with? Check all that apply.
A. Pollination
B. Seed dispersal
C. Fertilization

Answers

Answer: The steps in reproduction of angiosperms that animals assist with is

a.) Pollination

Explanation:

ANGIOSPERMS are flowering plants that forms the largest group in the plant kingdom. The angiosperms are more highly evolved than other plants because they have an abundance of water- conducting vessels and bear seeds which are protected within fruits. Fruits develop from the ovaries of flowers, the female reproductive organ of the angiosperms.

Pollination is only the first step in the process of sexual reproduction in flowering plants. It is followed by fertilization and development of the zygote. These steps change the flower into a fruit enclosing seeds. Pollination in flowering plants involves the transfer of pollen grains from an anther to a receptive stigma.

Pollination depends on external pollinating agents known as pollinators. These include

--> insects and

--> animals such as birds, squirrel,bats and snails.

Animals such as birds perceive red colour more clearly than insects. They are also larger than insects and unlike insects have a poor sense of smell. As a result, flowers of plants that are pollinated by birds are usually Res with no scent. While flowers pollinated by insects are scented and produce nectar. As they visit the flower, they become covered with the pollen from the mature anthers of the flower. These pollen grains are eventually transferred to the stigma of another flower of the same species leading to fertilization which is a step in plant reproduction. Therefore, pollination is a step in reproduction of angiosperms that animals assist.

Answer:

B. Seed dispersal

Explanation:

Seed dispersion is an ecological process very important in keeping ecosystemic biodiversity and in vegetal communities regeneration. There are many types of dispersion. But probably, zoocory is one of the most significant types of seed dispersion.

There are two types of zoocory:

Exozoocory: refers to the transport of seeds in the fur or feathers of animals.Endozzocory: refers to the ingestion of the seeds and the posterior excretion.

By endozoocory, herbivores are significant not only for dispersing the seeds but also for scarifying them. When seeds pass along the digestive system of the animals, the whole digestive process eliminates or debilitates the cuticle and other external structures, increasing the proportion and speed of germination.

Many vertebrates are involved in seed dispersion, but birds and frugivorous bats play an important role in dispersing seeds far away from the parental plant, playing an important role in the natural ecosystem regeneration processes.

b) In how many cases would you fail to know the first two nucleotides of the codon if you knew which amino acid is specified by it?

Answers

Answer:

a) 28 cases

b)  3 cases

Explanation:

a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc.

b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these 3 cases would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.

The enzyme could become spatially distorted, thus reducing the ability of the active site to catalyze the reaction. Tight enzyme-substrate binding will reduce the forward rate constant for the reaction. Tight binding of the enzyme to its substrate will pull the substrate out of solution, thus decreasing the driving force for the forward reaction. Tight binding of the enzyme to its substrate will result in the enzyme-transition state complex being higher in energy than with weaker binding. All of the above.

Answers

Answer:

All of the above.

Explanation:

All the given options are the potential disadvantage of an enzyme that have a very high affinity for its substrate.

The enzyme can be distorted spatially and thus reduces the ability to catalyze the reaction of the active site.

The tight binding of an enzyme to a substrate results in enzyme transition state complex which is higher in energy.

The tight binding also pulls the substrate out of the solution and decreases a driving force in the forward reaction.

This animal has a protostome developmental pattern and a trochophore larva. Identify the major clades that this animal belongs to

Answers

Answer:

Lophotrochozoans (it is a protostome)

Explanation:

Lophotrochozoa is a group (clade) of protostome animals, i.e. animals that undergo a developmental pattern in which the blastopore develops into the mouth. Lophotrochozoa clade includes bryozoans, annelids, molluscs, brachiopods, and platyhelminthes. Most lophotrochozoans have either a lophophore or trochophore larvae during the planktonic stage. A trochophore larva is a marine planktotrophic larva with several bands of cilia that form the locomotory organ (i.e., the prototroch), which is only found within the Lophotrochozoans.

When the larva and the adult form of an organism are different from each other this type of development is called indirect development. For example Porifers and platyhelminthis.

Why do you think the parts of the body have different sensitivities? Write an argument to support your explanation.​

Answers

The four senses of sight, hearing, smell, and taste are located in specific parts of the body.

The sense of touch is located throughout the body, in your largest organ, the skin. The sense of touch originatees in the bottom layer of your skin called the dermis.

The dermis is filled with many tiny nerve endings that give you information about the things your body is touching. Nerve endings do this by carrying the information to the spinal cord, which sends messages to the brain where the feeling is registered.

The nerve endings in your skin can tell you if something is hot or cold. They can also feel if something is hurting you. Your body has about twenty different types of nerve endings that all send messages to your brain. However, the most common receptors are heat, cold, pain, and pressure or touch receptors. Pain receptors are probably the most important for your safety because they can protect you by warning your brain that your body is hurt.

Some areas of the body are more sensitive than others because they have more nerve endings. It hurts when you bite your tongue because the sides of your tongue have a lot of nerve endings that are very sensitive to pain. Your tongue, however, is not as good at sensing hot or cold. That is why it is easy to burn your mouth when you eat something really hot. Your fingertips are also very sensitive. People who are blind use their fingertips to read Braille by feeling the patterns of raised dots on their paper.

Decomposers are living organisms that breaks down other living and non-living things into smaller parts. ... Decomposers can recycle dead plants and animals into chemical nutrients such as carbon and nitrogen that are released back into the soil, air and water as food for living plants and animals.

Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

Decomposers, such as bacteria, fungi, termites, and earthworms, are scavengers that feed on the organic material found in dead producers and consumers. They break down the organic material to the nutrient level. Nutrients in soils are essential for producers to grow. Nutrients include nitrogen, carbon, and phosphorous. Thus, dead consumers (and producers) are recycled back into new producers.

In Wakanda, in a population in Hardy-Weinberg equilibrium, the frequency of the single recessive allele controlling vibranium assimilation, which affects superhuman abilities, is 0.2. What is the percentage of the population that is heterozygous for this allele

Answers

Answer:

32%

Explanation:

Hardy–Weinberg equilibrium is also known as Hardy–Weinberg law. The idea of Hardy–Weinberg equilibrium is about the frequency of alleles in a population. The frequency of an allele in the population will always remain the same in a population if that population is not influenced by any evolutionary consequences.

Hardy–Weinberg equilibrium binomial expression formula is p2+2pq+q2=1. Suppose the frequency of recessive allele = q.

and another normal allele is = p

Here Q = 0.2 so P will be 1- Q or 0.8

By Hardy–Weinberg equation p2+2pq+q2=1, Here 2pq denotes the frequency of recessive allele, so 2pq = 2 × 0.2 × 0.8 = 0.32, if converted into percentage it will be 32%.

X-ray crystallography is a very important process that is used to help identify the structure of molecules. What exactly does this process show?

Answers

Answer:

can reveal the precise three-dimensional positions of most atoms in a protein molecule because x-rays and covalent bonds have similar wavelength, and therefore currently provides the best visualization of protein structure.

Because x-rays and covalent bonds have comparable wavelengths, they can now give the finest imaging of protein structure because they can reveal the precise three-dimensional locations of the majority of atoms in a protein molecule.

What is X-ray crystallography?

X-ray, a scientific technique called crystallography may be used to map out the atoms of a crystalline material in three dimensions. By using most crystalline materials' interatomic gap as a diffraction gradient for x-ray radiation, which has wavelengths on the order of 1 angstrom, this method makes use of the interatomic spacing of most crystalline solids.

Wilhelm Rontgen made the discovery of x-rays in 1895. Up until 1912, there remained disagreement about whether x-rays constituted electromagnetic energy or particles. Researchers recognized that this light's wavelength would need to be in the range of 1 Angstrom (A) if the wave theory was accurate.

It would be necessary to use a gradient with separation on the same order of magnitude as the light for diffraction and measurement of such tiny wavelengths.

To diffract the x-ray beams, the arrangement of the atoms must be in an ordered, periodic form. The specific arrangement of atoms in that crystal is then revealed through a sequence of mathematical computations to create a diffraction pattern. The principal technique still in use today for studying the structure and bonding of organometallic compounds is X-ray crystallography.

Therefore, since x-rays and covalent bonds can display the precise three-dimensional locations of the majority of atoms in a protein molecule, they provide the best imaging of protein structure currently achievable.
