Explanation:

fam what is that

The mRNA processed transcript will be: AUG GCA UAU UUU UUA AUU GAA UCU GCA CGA GAA AAU GAA GCA ACU UAG.

In genomics, transcription is the method of generating an RNA copy of a gene's DNA sequence. This copy, known as messenger RNA (mRNA), transports the protein information encoded in the gene's DNA.

This RNA copy, known as messenger RNA (mRNA), contains the genetic information required for a cell to produce proteins.

It transports information from the cell's nucleus to the cytoplasm, where proteins are produced.

The entire gene is copied into a pre-mRNA, which includes exons and introns, during transcription. Introns are removed and exons are joined to form a contiguous coding sequence during the RNA splicing process.

Thus, as the introns are getting removed completely, the mRNA sequence for the given DNA sequence will be: AUG GCA UAU UUU UUA AUU GAA UCU GCA CGA GAA AAU GAA GCA ACU UAG.

Answer:

1 deltoid: striated

2 triceps: striated

3 heart: cardiac

4 sartorius: striated

5 intestine: smooth

6 veins: smooth

7 biceps: striated

8 trapezius: striated

9 stomach: smooth

10 gastrocnemius: striated

Explanation:

Striated muscle is a type of tissue composed of repeated functional units called sarcomeres, which are the basic contractile unit of the muscle fiber. The striated appearance is caused by repeating bands of actin and myosin proteins. Striated muscle tissue is subdivided into two major parts: 1-cardiac muscle and 2-skeletal muscle. Skeletal muscle is a highly dynamic tissue that is mostly attached by tendons to the bones in the skeleton. This voluntary tissue (skeletal muscle tissue) is composed of multiple fascicles or bundles of muscle fibers. Moreover, cardiac muscle tissue, also known as myocardium, is a type of striated muscle that contracts and releases involuntarily, composed of cells called myocytes present in the heart. Finally, smooth muscle is a type of involuntary and non-striated muscle tissue localized within the walls of organs/structures (i.e., intestine, esophagus, stomach, uterus, urethra, bladder, blood vessels, etc.).

Answer:

The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. As you have learned, mitosis is the part of a cell reproduction cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus.

Explanation:

The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. As you have learned, mitosis is the part of a cell reproduction cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus.

Answer:

In general, mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components.

Explanation:

The different stages of Mitosis all together define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two genetically identical daughter cells.Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions. Homologous chromosomes are separated in the first division.

10% of the energy stored in the producer's tissues is used by herbivores. Option C. Producers provide primary consumers with the chemical energy they need.

The trophic web is the interaction between different organisms involving the transference of energy when some of them feed on the other ones.

The ones placed at lower levels pass energy to the ones at the higher levels. Only 10% of the energy stored in each individual's tissues is transmitted to its predator. The remaining 90% of energy is released into the environment.

Organisms at each level feed on the preceding one and become food for the next one.

• The first link corresponds to a producer organism -autotroph-.

• The following links are the consumers -heterotrophs-: herbivores and carnivores.

• The last links are the decomposers that degrade organic matter from dead organisms.

Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.

Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Options:

A. Producers and primary consumers compete with each other for food sources ⇒ False. they do not compete. Producers take energy from the sun, while primary consumers take energy from producers.

B. Primary consumers eat secondary consumers, which rely on producers for food. ⇒ False. Secondary consumers feed on primary consumers.

C. Producers provide primary consumers with the chemical energy they need. ⇒ False. True. 10% of the energy stored in the producer's tissues is provided to primary consumers -herbivores-.

D. Primary consumers provide producers with the chemical energy they need.​⇒ False. Primary consumers use the energy from the producers.

The correct option is C. Producers provide primary consumers with the chemical energy they need.

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:

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.

Answer:

Plums have high concentrations of anthocyanin, which absorbs light between 500 nm and 600 nm but reflects blue-purple wavelengths.

Spinach leaves have a high concentration of chlorophylls, which absorb light of lower wavelengths but reflect green ones.

Explanation:

White light is a mixture of the visible spectrum of light. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.

The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.

The green color is normal in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. Blue wavelengths a between 420-470 nm. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.

On the other hand, many fruits -blueberries, cherries, plums, or grapes- and flowers express a high concentration of anthocyanin, a pigment that reflects spectrums of red, blue, and purple wavelengths. This pigment absorbs light of 250, 370, and 500-600 nm. Yellow and orange wavelengths correspond to 500-600 nm.

Plums:

Spinach leaves:

(a) Plums have high engagements of anthocyanin, which absorbs light between 500 nm and 600 nm but reflects blue-purple wavelengths.

(b) Spinach leaves have a high engagement of chlorophylls, which absorb light of lower wavelengths but reflect green ones.

Explanation:

T cells are a type of white blood cells (leukocytes) that play a fundamental role in the immune system by determining the specificity of the immune response to specific antigens. In T cells, the remodeling of the actin cytoskeleton is critical for the movement of these cells through different tissue environments and for adjusting their behavior during the scanning of antigen-presenting cells. The actin cytoskeleton acts as a physical platform for intracellular signaling events that occur at the immunological synapse formed between a T cell and an antigen-presenting cell, thereby contributing to T cell activation.
