Answer 2

According to the electronic configuration, when hydrogen shares electrons with oxygen , hydrogen atom has 2 electrons and oxygen atom has 8 electrons.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each? Meiosis has four cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has two cell divisions and results in two identical daughter cells. Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells. Mitosis occurs in gametes to increase genetic variation in daughter cells, while meiosis occurs in body cells for growth and repair. Mitosis produces genetic variation in daughter cells and increases the number of chromosomes, while meiosis occurs in body cells for growth and repair.

Answers

Answer:

Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.

The main differences would be that Meiosis has 4 cell divisions and Mitosis had 2 cell divisions. Meiosis results in 4 haploid daughter cells and Mitosis results in 2 identical daughter cells.

Another big difference between the two could be that Meiosis produces genetic variation in the daughter cells and increases the number of chromosomes whilst Meiosis occurs in body cells for growth and repair. Each process has a different job.

how does increasing the size of the habitat affect carrying? explain your answer. recall the scenarios: 0-15 years, little land; 15-30 tears, moderate land;30-45 years, ample land

plzzz helpp ​
I meant years not tears

Answers

Answer:

so basically carrying capacity is "the amount of organisms a specific environment can support", so if the environment is increased, most likely, more space and food will be available, which means the environment can hold more organisms, causing the carrying capacity to increase

Explanation:

what I just said lol

Answer:

Increasing the habitat size will increase the carrying capacity. Carrying capacity is the maximum amount of organisms a habitat and its resources can carry. So if the habitat expands and more resources become available, the population would expand. As you can see for the first 15 years, when it was the little land, there was only about () rabbits, but as the land grew throughout the years, the rabbit population grew. 15-30 years with moderate land had around () rabbits, and the ample land in years 30-45 had around () rabbits, a little over two times the amount the little land had.

D. convert solar energy into chemical energy.

Explanation:

Chloroplasts are the organelles that carry out photosynthesis. They contain chlorophyll, which traps light energy from sunlight to power chemical reactions that produce glucose.

The solar energy is converted into chemical energy, which is used to synthesise glucose, along with carbon dioxide and water. The reactions produce glucose and release oxygen as a byproduct.

Create an example in which a mutation entered the gene pool and due to predator pressure. Becomes predominate. For example, think about how the color of the Peppered moths during the industrial revolution changed. The moths were light in color, but due to all the pollution from industry the trees they lived on turned dark making the light moths an easy target for birds. The moths with the mutation for dark color were able to blend with the darker bark and survived. These dark colored moths passed their genes on to their offspring and over a relatively short period of time most of the moths became dark. When the pollution decreased, the lighter colored moths predominated once again.
*Write a paragraph or so it can be a little under. Ill give you brainiest.*

Answers

Answer:

The population of light colour Peppered moths decreases and dark Peppered moths increases.

Explanation:

During the industrial revolution, the population of light colour Peppered moths decreases and dark Peppered moths increases because due to industrial revolution, air pollution increases which spreads a black dust on the trees and as a result the light colour Peppered moths can easily be seen in the dark by its predator and feed on them while dark colour Peppered moths can't be seen in the dark so the predator is unable to feed and as a result the population of dark colour Peppered moths increases.

During an experiment to determine if people with more symmetrical body features have a lower incidence of disease, a researcher first measures the length of several bones in the subject's hands and arms. The device used to measure length does not display a readout of the measurement taken. Instead, a wire connects the measuring device to a computer that records the data. The computer monitor is kept out of sight of the subject and the researcher. Why is such an elaborate device used?a. So that the subject will not know if he or she is part of the control group.b. So that the experiment will be repeatable.c. So that the subject will not be injured by the experiment.d. So that the identity of the subject will remain anonymous.e. So that the measurements are not biased by the researcher.

Answers

Answer:

e

Explanation:

The main reason such an elaborate device was used would be to eliminate any element of bias by the researcher.

It is important to eliminate biases when taking measurements so as to ensure the accuracy of the data and the overall outcome of the experiment. If a simpler device had been used in which the researcher manually records the length of the bones, it is possible to knowingly or unknowingly introduce biases or random error into the experiment which will impact the integrity of the data and the outcome of the experiment.

Answers

Answer:

After 3 half lives 12.5 g of C-14 left

Explanation:

Given data:

Mass of C-14 = 100 g

After 3 half lives mass left = ?

Solution:

At time zero = 100 g

At first half life = 100 g/2 = 50 g

At second half life = 50 g/ 2 = 25 g

At third half life = 25 g/2 = 12.5 g

Thus, after 3 half lives 12.5 g of C-14 left.

the number of consumer can never exceed the number of producer in nature why​

Answers

Answer:

The number of consumer can never exceed the number of producer in nature because there is a limited amount of producer in the nature so the consumers is the one who eats a producer !

When the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.

What are Producers and Consumers?

Producers are plants that make their own food, the energy they need to grow, reproduce, and survive. They are making their own food which makes them special. These are the only living things on Earth that can make their own source of food energy with the help of sunlight, water and air.

Consumers make up the upper trophic level. Unlike producers, they cannot make their own food. They obtain their food by eating plants or other animals, while some eat both.

Scientists distinguish between several types of consumers. Primary consumers form the second trophic level.

Thus, when the number of consumers increases, producers disappear due to overconsumption and consumers disappear due to lack of food and the ecosystem is destroyed. Therefore, in nature the number of consumers can never exceed the number of producers.

What are some of the ways that parasites have adapted to transmission between hosts and resisting the host’s attempts to get rid of the parasite? How do these particular developments help the parasite?

Answers

Answer for you
Organisms depend on other species for resources such as nutrients. Parasites live in or on another organism, which is called the host. The parasite takes what it needs from the host but the host receives nothing in return and often suffers as a result. An example of parasitism is the relationship between fleas and dogs. Fleas live on dogs and feed on their blood. The dog receives no benefit but the fleas are provided with food and a habitat. Fleas attach themselves to hairs and can spread from one host to another by jumping huge distances.

What is emigration?

Emigration is the act of relocating away from a resident country or place of residence (to permanently leave a country). Contrarily, immigration refers to the flow of individuals from one country into another (to permanently move to a country).

A migrant leaves their home nation and moves to their adopted one. Emigration and immigration thus both describe migration, but from the perspectives of various nations.

Demographers look at the push and pull factors that cause people to be drawn to one place and pushed away from another. Desires to escape unfavorable situations, such as scarcity of land or employment opportunities, or unfair treatment, are possible.

In other cases, researchers use natural experiments in which the dependent variable (typically a measure of organism health) is measured under differing contexts that are not manipulated. Say, for example, that an accidental chemical spill contaminates five ponds. To determine the possible effects of the toxic chemical on frogs, a researcher could compare the hatching rate of frog eggs laid in those five ponds to the hatching rate of eggs laid in five uncontaminated ponds nearby. This would be an example of a natural experiment because concentrations of the toxic chemical in the ponds were not controlled by the experimenter, but rather resulted from the chemical spill.
