Answer:

Mitosis, Meiosis, and both are written below

Explanation:

Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas

Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages

Both: Chromosomes need to replicate before the whole process begins, a form of reproduction

Answer:

The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. Gas exchange in the lungs occurs in millions of small air sacs; in mammals and reptiles these are called alveoli, and in birds they are known as atria. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is the trachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves the muscles of respiration.

Answer:

1. Archaeologist use radioactive isotopes to determine the ages of various objects, rocks and materials. This is called radioactive dating. Radioactive isotope Carbon-14 is widely used for this dating process.

2. Scientists use radioactive isotopes in agriculture to monitor or study the uptake and use of essential nutrients by plants from the soil. This helps to determine viability, productivity and nutritious ability of the plants on a piece of land.

3. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events. ... Atoms of the same element but with different number of neutrons are called isotopes of that element.

Answer:C: Determine the age of ancient artifacts.A: Understand the biological and chemical processes in plants.B: Determine the age of rocks and fossils.

Cell Cycle

Explanation:

geologic time use the layer of Rock to describe relationship of events and their sequence chronological order over the history of Earth the layering is a result of the buildingup tiny beats of rocks sediments or Lava cooling at the surface of many years think think of it like a stock of pancakes-the bottom layer is the one that was placed first and therefore is the oldest. the sediments that create the layer of the earth as said one or top of the other

Answer: It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.

Explanation:

Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.

Explanation:

Answer:

Many predators have adaptations that help them survive in the wild.  For example, the snake shown below has camoflauge coloring to look like its surroundings.  This gives it the element of surprise when going to attack its prey.  These adaptations help the predator in hunting for food.  Predators have "weapons", or adaptations, that help them hunt and kill prey. Predators' three main "weapons" are teeth, claws, and jaws.  The lion below has all 3 of these "weapons" or adaptations that are used for catching its prey. A lion has sharp claws for catching and grabbing hold prey such as a zebra, and strong jaws and teeth for biting and killing the zebra and for ripping off and chewing the meat.

Answer:

the cell copies or replicates its chromosomes and then splits the copied chromosomes equally to make sure each daughter cell has a full set.

Answer:

Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies or "replicates" it's chromosomes and then splits the copied chromosomes equally to make sure that each. daughter cell has a full set.

Answer:

Some possible affects of contaminated water on the health of an individual are, reproductive problems, gastrointestinal illness, cancer, and neurological disorders. Contaminated water can be caused by natural chemicals and minerals like radon, uranium, etc. Contaminated water could also be caused like wastewater releases or sewers overflowing. Some infectious agents involved in the related diseases would be bacteria, viruses, helminths and even protozoa. These diseases can spread through drinking the water, airborne, or just contact with the water or infectious agents.

Answer:

The question is incomplete, I found a matching question online:

At the end of their biology unit, 7th grade students were asked to make a glossary of biological terms. Which student did the best job of defining the word "heredity"?​

A) Kendall- Heredity is the study of chromosomes and the genes that they contain.

B) Carla- Heredity is the passing of genetic information contained in chromosomes from one generation to the next.

C) Joseph- Heredity is the study of human characteristics passed down from parent to offspring.

D) Devon- Heredity is the reason that tall parents will usually have tall children.

Answer:

The correct answer is:

Carla- Heredity is the passing of genetic information contained in chromosomes from one generation to the next. (B)

Explanation:

Heredity, also known as inheritance is the passing down of genetic traits and genetic information from parents to their offspring through reproduction (sexual or asexual), and this information is contained in DNA materials called chromosomes.

Carla's definition most appropriatly captures the context of genetics, while Kendall and Joseph rather defined "genetics", which is the study of heredity.

Devon did not give a definition, but rather an example.

Answer:

el ATP es la moneda energética que la célula utiliza para llevar a cabo diversas funciones metabólicas (incluida la reproducción)  

Explanation:

La adenosín trifosfato (ATP) es la principal fuente de energía para la mayor parte de los procesos celulares. La hidrólisis del ATP libera energía química almacenada en los enlaces de fosfato de la molécula, la cual es utilizada por la célula para llevar a cabo diversas funciones, incluida la reproducción. La hidrólisis de ATP genera en primera instancia adenosín difosfato (ADP) y un grupo fosfato libre (ortofosfato), esta es una reacción exergónica que libera una enorme cantidad de energía la cual es utilizada por la célula para llevar a cabo diversas funciones metabólicas incluyendo la síntesis de macromoléculas tales como, por ejemplo, proteínas del huso mitótico requeridas durante el proceso de división celular. El ADP también puede hidrolizarse para liberar energía, con la consecuente producción de adenosín monofosfato (AMP) y un segundo fosfato libre.

Answer:

Four reactions that occur in kreb cycle transfer electrons from substrate to an electron accepting enzyme.

Explanation:

There is four such a response in which electron is transported from substrate to electron-allowing enzyme. In three of those, NAD+ is decreased to NADH and in one FAD decreases to FADH2. The TCA cycle is likewise recognized as the Krebs cycle after the signature of English biochemist Hans Kreb who illustrated the pathway in the 1930s.

Explanation:

DNA replication is the process by which DNA makes a copy of itself during cell division. ... The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'. The two separated strands will act as templates for making the new strands of DNA.

Answer:Tertiary consumers eat the secondary consumers and are usually carnivores (meat eaters).Secondary consumers are organisms that eat primary consumers for energy. Primary consumers are always herbivores, or organisms that only eat autotrophic plants. However, secondary consumers can either be carnivores or omnivores. Carnivores only eat other animals, and omnivores eat both plant and animal matter.

Answer:

Negative

Explanation:

Gravitropisms. Phototropism is a response to the stimulus of light, whereas gravitropism (also called geotropism) is a response to the stimulus of gravity . When the stem grows against the force of gravity (upwards), this is known as a negative gravitropism.

Answer:

negative

Explanation:

this is because negative gravitropism is when a plant grows away from gravity (like moving upwards). then, positive gravitropism is when the roots of a plant move grow downwards.
