Esta teoría hace referencia al movimiento actual de las placas que sustentan los continentes y que se desplazan a lo largo de millones de años. En toda la historia geológica de la Tierra, los continentes no han estado siempre en la misma posición. Existe una serie de evidencias que veremos posteriormente que ayudaron a Wegener a refutar su teoría. El movimiento se debe a que continuamente está formándose nuevo material procedente del manto. Este material se crea en la corteza oceánica

Answer:

the answer is (C) haploid + haploid = diploid

Explanation:

edge 2021

Haploid+ Haploid = Diploid represents fertilization. So, the correct option is (C).

Fertilization is defined as the process in which two gametes where one male and one female first form a zygote and then lead to the development of an embryo.

These germ cells are cells that give rise to gametes – either egg cells that are female gametes or sperm cells that are male gametes.

These germ cells are the only cells that can undergo both mitosis and meiosis. These are the diploid cells present in the gonads. After meiosis, haploid gametes are produced. In fertilization two haploid gametes fuse (n+n) and form a diploid zygote (2n)

Thu, Haploid+ Haploid = Diploid represents fertilization. So, the correct option is (C).

Answer:

Respiratory System: The respiratory system's main job is to move fresh air into your body while removing waste gases.

Nostril: To warm air on inhalation and remove moisture on exhalation.

trachea: Serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.

bronchiole: To deliver air to a diffuse network of around 300 million alveoli in the lungs.

alveoli: To exchange oxygen and carbon dioxide molecules to and from the bloodstream during breathing.

pharynx: Helps the respiratory system by allowing air to make its way to the respiratory tract.

larynx: Produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.

lungs: To help oxygen from the air we breathe enter the red cells in the blood.

ribs: To aid respiration and help protect the lungs.

diaphragm: Contracts and flattens when you inhale. Creates a vacuum effect that pulls air into the lungs, and relaxes when exhaling.

According to the graph, the regions that are expected to reach a population of 50 million people in the year 2040 are (A). Mexico, Central America, the Caribbean island, and South America.

Answer:

Hutton's Unconformity

At Siccar Point, during the lower Silurian Llandovery epoch around 435 million years ago, thin beds of fine-grained mudstone were laid down gradually deep in the Iapetus Ocean, alternating with thicker layers of hard greywacke formed when torrents swept unsorted sandstone down the continental slope. Siccar Point is a rocky promontory in the county of Berwickshire on the east coast of Scotland. It is famous in the history of geology for Hutton's Unconformity found in 1788, which James Hutton regarded as conclusive proof of his uniformitarian theory of geological development.

Answer:

Roughages increase fecal volume and promote peristalsis

Explanation:

Constipation refers to the condition in which bowel evacuations occur infrequently, leading to health problems. Some of the most common causes of constipation include 1-insufficient intake of dietary fibers or roughages, 2-poor hydration, 3-lack of physical exercise, 4-abuse of laxatives, etc. Dietary fibers are divided into two classes based on their water solubility: soluble and insoluble. These fibers represent the part of plant foods that the body can't digest, which absorbs and retains water (soluble fibers) as foods pass through the bowel and create bulk (insoluble fibers), thereby leading to regular bowel habits.

Answer:

Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.

Explanation:

Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.

Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.

Answer:

Which of these factors would most likely strengthen the effectiveness of CITES?

Answer: Funding for on-the-ground enforcement

Answer:

During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Answer:

The correct answer is - helps speed up the process of transcription.

Explanation:

RNA polymerase binds to the DNA sequence and copy a single DNA sequence into RNA and helps a single gene to produce hundreds or even thousands of RNA molecules during transcription.

It helps in the speed up the transcription by copying the sequence and producing mRNA for translation process later.

Aquaporins result in a combination of positive charges intracellularly and negative charges extracellularly

What are Aquaporins?

Aquaporin is a group of membrane proteins found in cell membranes and selectively permit water to pass into and out of the cell. Also known as water channels, aquaporins are integral membrane pore proteins. Aquaporins are found in plants, bacteria and animals. They are observed in the vacuolar membranes and plasma membranes. The basic function of most aquaporin is to transport water across cell membranes in response to osmotic gradients created by active solute transport. Aquaporins enable passive transport which means they allow the movement of molecules across a cell without using energy.

The SARS-CoV-2 non-structural protein 1 (Nsp1), also referred to as the host shutoff factor, suppresses host innate immune functions. By combining cryo-electron microscopy and biochemistry, we show that SARS-CoV-2 Nsp1 binds to the human 40S subunit in ribosomal complexes, including the 43S pre-initiation complex and the non-translating 80S ribosome. The protein inserts its C-terminal domain into the mRNA channel, where it interferes with mRNA binding. We observe translation inhibition in the presence of Nsp1 in an in vitro translation system and in human cells.

Answer:

Yeast cells likely do not have receptors that bind to this specific water-soluble mouse hormone

Explanation:

Receptors are molecules capable of binding specific signaling molecules (i.e., ligands). For example, steroid receptors can only bind to specific steroid hormones (e.g. estrogen, progesterone). Plasma membrane receptors are protein receptors that bind to water-soluble ligands. These receptors are embedded in the cell plasma membrane and usually contain several transmembrane domains. Examples of cell membrane receptors include G protein-coupled receptors (GPCRs), enzyme-linked protein receptors and ion channel receptors.

Answer:

if  An individual has an extra chromosome in every one of its cells, the mutation that must have occurred is A non-disjunction mutation in the gamete of one of the parents

If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, the mutation that must have occurred is A. A nondisjunction mutation in the gamete of one of the parents.

Down syndrome simply means a genetic disorder that is caused when there's an abnormal cell division that then leads to extra genetic material.

The effect of Down syndrome is the fact that it leads to an intellectual disability, developmental delays, and a distinct facial appearance.

The mutation that has occurred with someone that has a Down syndrome is the nondisjunction mutation in the gamete of one of the parents.
