Each constellation is a region of the sky, bordered by arcs of right ascension and declination. ... Together they cover the entire celestial sphere, with their boundaries adopted officially by the International Astronomical Union in 1928 and published in 1930.

So I would say its A : Boundary

Explanation:

- Eijiro <3

Love the pfp by the way! :D

The International Astronomical Union (IAU) defines a constellation by its boundary. The correct option is A.

In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.

The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.

The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.

Thus, the correct option is A.

Answer:

part 1: Carbon dioxide

part2: combustion, respiration

part3:

- carbon in the atmosphere is removed by green plants and phytoplanktons in water bodies through the process of photosynthesis.

-The CO2 is then incorporated into carbohydrates such as sugar or starch and eventually to lipids and proteins .

-The plants are later on consumed by the animals and the organic matter in the plants are digested b,absorbed and make up the animal tissues.

-The formation of fossil fuels(fossilization) and limestone also removes CO2 from the atm.

-CO2 in the atm also dissolve in water to form acid rain thus removing CO2 from the atm.

- CO2 is added into the atm by respiration. During respiration plants and animals oxidize carbon compounds in their cells breaking them to CO2 and water which are later excreted into the atmosphere.

- When plants and animals die their remains are broken down by saprophytic organisms converting the carbon compounds to CO2 which is released into the atm.

- When eruption occurs gases are released into the atm amongst which is CO2 thus increasing its conc in the atm.

Explanation:

From what I could understand the first part of part three talks abt the removal of carbon dioxide from the atm while the second part talks abt its addition. I hope I got it right.

An animal is then able to walk or run because the muscles of the muscular system work with the bones of the skeletal system. The musculoskeletal system is what enables movement.

The skeletal system of the body has been composed of the bones and cartilage and they will perform many different types of function in the body of the organism. The cartilages along with the bones form the structural framework of the body. It also helps in the performing locomotory functions of the body. The brain signals the body of an animal to move by transmitting electrical impulses through the neurons.

It has the skeletal system of the body that helps in the walking, bending, sitting and as well as other movements of he body. It has been also serves as the barrier between the outer environment and internal organs and protects them from any exertion and shock.

Temperate Deciduous Forest Biome

Temperate Deciduous Forest Biome

This biome is named for the dominant trees that drop their leaves during the winter months. These forests may have an overstory of 20–30 m tall trees, an understory of 5–10 m trees and shrubs, a shrub layer around 1–2 m in height, and a ground layer of herbaceous plants.

Explanation:

Answer:

C

Explanation:

autsomsal means that it is not x-linked/ realted to gametes. Dominate means that it needs only one X to get the trait

Using the punnet square

             X       x

      x     Xx   xx

      x     Xx   xx

there is 2 X which means there is a 50% change that their child will get the trait

In the punnett square analysis, each child has a 50% chance of inheriting the trait.

The mother Xx has the trait and the father xx doesn't.

Using the punnet square

Xx                 xx

Xx   Xx  xx  xx

There are just two traits which are Xx and xx which are in equal frequency

and proportion.

This therefore means that the children have a 50% chance of getting the trait.
