For larger distances such as the distance between objects in the far reaches of our galaxy astronomers ensure in units of?

Answers

Answer 1

Answer:

Lightyears

Explanation:

When dealing with very large interstellar distances, astronomers do not use the regular miles, kilometers, or meters we are used to. This is because they are just too small to be used as a metric when measuring such large distances. As a matter of fact, the earthly number system will quickly be exhausted when trying to measure some of these interstellar distances.

Instead, astronomers make use of Lightyears. Lightyears are defined by the distance traveled by an object moving at the speed of light if it was moving constantly at that speed for one year.

This can properly be used to estimate interstellar distances. since its value is very large. 1 lightyear = 9,461,000,000,000 Km

If we say that our closest star is 9 lightyears away, we are saying that it will take an object moving at the speed of light 9 years to travel from that star to our planet.

Answers

Answer:

Malaria-mosqitoes

Cholera- contaminated food and water

pneumoni- cought droplets

Explanation:

malaria-people get malaria by being bitten by an infective female Anopheles mosquito. Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken from an infected person.

Cholera-The cholera bacteria is passed through feces (poop). It is spread by eating or drinking food or water contaminated by the feces (poop) of an infected person. This occurs more often in underdeveloped countries lacking proper water supplies and sewage disposal.

Pneumonia-The viruses and bacteria that are commonly found in a child's nose or throat, can infect the lungs if they are inhaled. They may also spread via air-borne droplets from a cough or sneeze. In addition, pneumonia may spread through blood, especially during and shortly after birth

C. breaks down lipids, carbohydrates, and proteins from foods.
D. helps maintain homeostasis as materials enter and leave the cell​

Answers

D. Cell membranes are generally semi-permeable, which means that they allow some materials in (the ones they need to function) and out. Membranes also block materials that the cell doesn’t want or need from entering. Homeostasis essentially means “sweet spot” (not literally just a way to remember it). Hope this helps!

Hi! hopes this help :)

Three bird species share a habitat Bird A eats insects and plants seeds. Bird B drinks flower nectar. Bird C eats plant seeds. Drought occurs in their habitat, and that season's plants are wiped out entirely under this condition only Bird A survives, both birds B and C die due to the condition of resource scarcity.

What is resource scarcity?

In the ecology, resource scarcity was mainly represented by the two factors that are food and water which are primary resources for survival if anyone one resource is not available for the bird species it will affect its survival.

Therefore, due to the resource scarcity only Bird A survives, both birds B and C die.

Multicellular organisms grow in size by producing more

Answers

Is a capable to a certain living organisms.

Multicellular organisms grow in size by producing more cells by the process of mitosis.

What is Mitosis?

Multicellular organisms are the organisms which are made up of hundreds or thousands of cells. These organisms grow by the production of new daughter cells through the process of cell division.

Cell division is of two types: Mitosis and Meiosis. Mitosis is an equational division, in which one parent cell divides to form two daughter cells. Mitosis occurs in each and every cell except in the formation of gametes (germ cells).

Mitosis occurs by nuclear division and cytoplasmic division. Nuclear division include four phases which include prophase, metaphase, anaphase, and telophase.

what are some Major Characteristics Temperate Deciduous Forest

Answers

Answer:

The Temperate Deciduous Forest is a biome that is always changing. It has four seasons: winter, spring, summer, and fall. Constant rainfall and daylight saving hours also contribute.

Explanation:

Temperate deciduous forests get between 30 and 60 inches of precipitation a year, this helps keep the forest lush and green. When it comes to daylight savings in the fall, lack of sunlight can affect photosynthesis and the amount of sun the plant gets. Unlike the amazon forest, the temperate biome goes through all 4 seasons and has plant regeneration in the spring instead of constant vegitation.
