Explanation:

Natural selection is the process to which the various species and populations are able to adapt and change according the environmental changes. It is affected by three main factors that are variation, over population and adaption.

Variation: varion is one of the factor that pushes the population to change towards the beneficial variation in the population for their survivability and reproducing theirselves.

Overpopulation: over population increases the competition amon population and there fore there resources become limited so few have to change or their ways of utilizing resources.

Adaption: Adapting the change takes place due to any situation in environmental that put stress on the population allow them to adapt according the change or they will extinct.

Answers

Answer:

The sacrum articulates with the ilium.  

Explanation:

The sacrum is a bone formed by the sacral vertebrae, which have fused to give this bone. Above it articulates with the lumbar vertebra, below with the coccyx, which is the last section of the vertebrae column. Lastly, it articulates with the ilium at the sides. The ilium is one of the three bones that makes the hip bone. It is the largest one and in the upper part of the hip bone.

The ischium and pubis, which are the other two bones that form the hip bone, do not articulate with the sacrum, but they articulate with the ilium and with each other.

It supports the plant.

The main function of the structure identified as A in the picture is to synthesize the foods of the plants, which is the second option, as plant leaves are essential for the survival and growth of plants, enabling them to produce food, exchange gases, and regulate water balance.

What is the plant leaves function?

Leaves are the primary site for photosynthesis, the process by which plants use sunlight, water, and carbon dioxide to produce food (glucose) and oxygen. Leaves also play a crucial role in gas exchange, allowing plants to take in carbon dioxide and release oxygen during photosynthesis and release carbon dioxide and take in oxygen during respiration. Leaves are responsible for transpiration, the process by which water is absorbed by the roots and transported through the plant to the leaves, where it is released into the air through tiny openings called stomata.

Hence, the main function of the structure identified as A in the picture is to synthesize the foods of the plants, which is the second option.

Why do biologists classify

Answers

Answer:

Biologists classify organisms because:

Classification allows us to understand diversity better.  It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences. It enables us to understand how complex organisms develop from simpler organisms.  They are grouped under different categories to understand and study the features, similarities and differences between different living organisms. It is essential to understand the inter-relationships among the different groups of organisms. Classification forms a base for the development of other biological sciences.

The image below shows one of the earliest stages of DNA replication. What
role does helicase play in DNA replication?


A. Helicase breaks the hydrogen bonds and unwinds a section of DNA.

B. Helicase connects the floating nucleotides to the template strands.

C. Helicase checks the base pairs in each new strand of DNA.

D. Helicase bonds together pieces of DNA as new strands form.

Answers

Answer:DNA helicases are also called molecular motors. They unwind the DNA with the help of ATP hydrolysis, and thus facilitate the replication and transcription processes. ... Studies have suggested that DNA helicases may play a role in plant DNA recombination, as it is prominent during the meiotic prophase of plants.

Explanation:

Role played by Helicase in DNA Replication is to break down the hydrogen bonds and unwinds a section of DNA.

What is DNA?

DNA, or deoxyribonucleic acid, is the hereditary material in humans located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.

The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.

What is DNA Replication?

In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.

DNA replication occurs in all living organisms acting as the most essential part for biological inheritance and it is  essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA.

The cell possesses the distinctive property of division, which makes replication of DNA essential.

DNA is made up of a double helix of two complementary strands. The double helix describes the appearance of a double-stranded DNA which is composed of two linear strands running opposite to each other and twist together to form.

During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.

As a result of semi-conservative replication, the new helix will be composed of an original DNA strand as well as a newly synthesized strand.

Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.

What is the role of Helicases in DNA Replication?

Helicases are enzymes that bind and remodel nucleic acid or nucleic acid protein complexes.

Helicases are of two types- DNA Helicases and RNA Helicases.

Role of Helicases:

- Separate the double stranded DNA into single one to allow copying.

- Initiate synthesis at the origin of unwinding

- Helicases use the energy stored in a molecule called ATP, which serves as the energy currency of cells, to break the bonds.

- DNA helicases also function in other cellular processes where double-stranded DNA must be separated, including DNA repair and transcription.

- RNA helicases are involved in shaping the form of RNA molecules, during all processes involving RNA, such as transcription, splicing, and translation.

See the answer below

Explanation:

The phenomenon is best explained by the fact that the genetic codes are degenerates. In other words, more than one codon can specify for the same amino acid being carried by the tRNA.

The base-pairing rule between the third nucleotide of a codon and that of the anticodon on the tRNAs loosens off. For example, GUU, GUC, and GUA all specify for the amino acid valine while GCU, GCC, and GCA all specify for alanine.

The physiologic effects of ______ include blood vessel constriction and decreased cellular metabolism.

Answers

Answer:

The physiologic effects of cryotherapy include blood vessel constriction and decreased cellular metabolism.

Explanation:

Cryotherapy is a treatment that uses cold to aid in the process of injury healing. One of the effects of low temperatures is vasoconstriction. As a result, the pressure increases, modifying the blood's flow and aiding in the healing process since blood circulation increases. The low temperatures also decrease cellular metabolism reducing the amount of oxygen that the cell needs. As a consequence, the cells have a higher chance of survival after the injury.

The great hornbill and the toucan both eat the same fruit, insects, and nuts. They both live in the rainforest. Their large bills function to get food and also as warning coloration. Which of the following is a limiting factor to the toucan population?
overlapping breeding seasons
bill coloration
genetic variability
competition

Answers

The correct answer is D. Competition.

Explanation

A limiting factor is a term that refers to the scarcity factor of a resource that limits the development and evolution of a specific species or process. According to what is described in the question, it can be inferred that the limiting factor of toucans is competition because the great hornbill lives in the same tropical forest as the toucan, it feeds on the same foods as the toucan: fruit, insects, and walnuts. So, competition for the same resources is a limiting factor for toucans since the absence of food can affect their development. So the correct respect is the D. Competition.

Some broad-spectrum proteases (protein hydrolyzing enzymes) and nucleases (nucleic acid hydrolyzing enzymes) that function in eukaryotic cells have an optimum pH close to 5.0, whereas the cytosol of most cells is closer to pH 7.0. Which part of a eukaryotic cell might you predict to have a low pH suited to maximizing the activity of these enzymes

Answers

Answer:

lysosome

Explanation:

The lysosome is a membrane-bound organelle found in nearly all eukaryotic cells. The lysosome contains different types of enzymes (i.e., proteases, nucleases, glycosidases, lipases, phosphatases) which are required for the digestion of macromolecules and microorganisms, and recycle macromolecules in the cell. These enzymes are only active in acidic (lysosome) conditions, and they can be deactivated in case of lysosomal rupture because in the cytosol the pH is neutral to slightly alkaline (∼7.3–7.4).
