Answers

Answer:

what process moves water from the atmosphere to the ground

Answers

The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

what are nodes and inter nodes​

Answers

Answer:

Nodes are the regions on the stem from which leaves develop, while internodes are the regions between two nodes.

#indians

The nodes are the specific areas on the stem where the lateral bud is present from which the leaves, branches or flower buds grow out. In comparison, an internode is the distance between two consecutive nodes. The xylem and the phloem run through the internodes.

why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?

Answers

Answer:

Deletion mutations can affect the entire base sequence.

Explanation:

Answer:

Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.

Define the following types of sexual reproduction: Binary fission, budding. fragmentation, parthenogenesis​

Answers

Answer:

Binary fission-Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.

Budding-Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out from the yeast cell is called a bud.

Fragmentation-Fragmentation in multicellular organisms is a form of asexual reproduction in which an organism is split into fragments. Each of these fragments develop into matured organism, full grown individuals that are genetically and morphologically identical to their parents. 

Parthenogenesis-

Parthenogenesis is a form of reproduction in which an egg can develop into an embryo without being fertilized by a sperm. Parthenogenesis is derived from the Greek words for “virgin birth,” and several insect species including aphids, bees, and ants are known to reproduce by parthenogenesis.

Fermentation is a chemical process by which molecules such as glucose are broken down anaerobically. Therefore, option (A) is correct.

What do you mean by fermentation?

Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.

Moreover, fermentation occurs in the absence of oxygen (anaerobic conditions), and in the presence of beneficial microorganisms (yeasts, molds, and bacteria) that obtain their energy through fermentation.

Hence, fermentation reactions occur in the cytoplasm of both prokaryotic and eukaryotic cells. In the absence of oxygen, pyruvate does not enter the mitochondria in eukaryotic cells.

what are two organisms in the food web that have a predator-prey relationship? i need examples

Answers

Answer:

Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.

Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.

What do you mean by predator-prey relationship?

In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. The predator prey relationship develops over time as many generations of each species interact.

Predator and prey populations cycle through time, as predators decrease numbers of prey. Lack of food resources in turn decrease predator abundance, and the lack of predation pressure allows prey populations to rebound.

The relationships between predators and prey play an important role in structuring ecological communities, with predators influencing the dynamics of their prey in ways that cascade through ecosystems.

Compare how the nervous system and endocrine system work to send messages through the human body.

Answers

Answer:

Here is Your answer vote me as brainlist.

Explanation:

One of the most significant differences between the nervous system and endocrine system is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.

The nervous system uses electrical and chemical signals to quickly send messages through the body, while the endocrine system uses hormones to gradually send messages through the bloodstream.

What is nervous and endocrine system?

The nervous system uses electrical and chemical signals to transmit information rapidly and directly to specific target cells. This system is composed of neurons, which transmit impulses through the body, and specialized cells called neuroglia, which support and protect the neurons. The nervous system is divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord and the PNS includes the nerves that extend out to the rest of the body.

The endocrine system, on the other hand, uses hormones to transmit information more slowly and diffusely throughout the body. Hormones are chemical messengers that are secreted by glands and travel through the bloodstream to target cells. The endocrine system includes a variety of glands, such as the pituitary gland, thyroid gland, and adrenal gland, that produce hormones that regulate various physiological processes, such as growth, metabolism, and reproduction.

Which statement below best describes the role of mutations in evolution by natural selection?
A Mutations increase the genetic variation within a population, and each of the variants provides an advantage under different circumstances
B Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
C Mutations help stabilize the genetic variation within a population, and only one or two variants generally provide an advantage to individuals.
D Mutations help reduce the genetic variation within a population, and thus increasing the rate that new adaptations develop.

Answers

Answer:

B. Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time

The role of mutations in evolution by natural selection is option b. Mutations increase the genetic variation within a population.

Role of mutation in evolution:

The mutation is significant as the first step of evolution since it developed the new DNA sequence for the specific gene that developed the new allele.

Also, at the same time, it rise the genetic variation within the population also it provides as an advantage to individual

An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments show what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.

The three primary categories of scientific experiments are quasi-experimental, observational, and experimental (non-experimental). The most rigorous type of scientific investigation is experimental, often known as randomized control. The most control is present, as the name would imply.

Data are the facts and the observations gathered in an experiment.  Therefore, option B is correct.
