​

Answer:

more distant galaxies are moving away faster.

the shift towards red (Doppler effect like with sound on Earth) is the indication.

Explanation:

what did this have to do with biology ?

and by the way, this is also something I debate severely in scientific communities, because yes, the red shift is there. but "more distant" also means "more in the past", so that the data shows us actually that things in the past moved faster away. not necessarily today ...

Answer:

C.Silicon

Explanation:

By far, the most prevalent bulk material for solar cells is crystalline silicon (c-Si), also known as "solar grade silicon". Bulk silicon is separated into multiple categories according to crystallinity and crystal size in the resulting ingot, ribbon or water.

Cells are the basis of the survival of human beings. We, the living organisms are made up of cells. If cells won’t divide no new organisms would originate.

Cell division is the process by which a parent cell divides, when a mother cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

The existing cells will die and no new cells will be produced as there is no cell division.

Answer:

The answer is (A.

Explanation:

Answer:

A. Unicellular prokaryotes that live in dust. Monera.

B. Unicellular eukaryotes that line in pond water. Protist.

C. Multicellular eukaryotes that live all over the planet and consume food. Animals.

D. Unicellular prokaryotes that live in volcanic ash. Monera.

E. Multicellular eukaryotes that have cell walls and are heterotrophic. Fungi.

F. Multicellular eukaryotes that have cell walls and are autotrophic. Plants.

Explanation:

The 5 kingdoms are a way of classifying all living organisms on our planet, as each species inside a kingdom shares similarities with the other species in it.

Monera kingdom includes all of the prokaryotic organisms that exist, which includes bacteria and archaea. These beings are characterized by lacking a nucleus and membrane-bound organelles and having one single circular chromosome that is found in the center of the cell. They are unicellular. Example: escherichia coli.

Protists are the most primitive eukaryotes that exist, most of them are unicellular and microscopic, but possess a nucleus and specialized organelles like the rest of the eukaryotes have. Example: yeasts.

Fungi and Plants are quite similar, they are multicellular eukaryotes that have cell walls. Their main difference relies on the way they obtain nutrients: fungi are heterotrophs, they feed off living things; plants, however, are autotrophs and realize photosynthesis (they do not need to feed). Fungi and Plants also reproduce differently: fungi reproduce through spores; plants can reproduce sexually or asexually. Fungi example: amanita; plant example: cactus.

Animals are multicellular eukaryotic organisms that reproduce sexually and are heterotrophs (some feed off plants, some feed off other animals). They are characterized by their ability to move. Example: horse.

1. It's because when they talk to girls (Not all), they fill their head with all sorts of doubts and worries and then feels nervous as a result.. like for example they could be thinking "Am I making the right impression? Am I too annoying? What does she think of me?"

Answer:

The digestive system, the circulatory system, and the muscular system work together and process and obtain nutrients from food. The skeletal system, the endocrine system, and the lymphatic system also work with the digestive system and process those nutrients.

Answer:

I don't know your reasons on how you would feel about becoming an astrobiologist but this is what I found and my feelings.

Explanation:

The Perseverance twin is called Optimism.  This has all of the same electronics as Perseverance and it’s important to have a twin so that they can test things before they operate Perseverance.  When they do land on Mars they need the twin to test out all of the sequences and plan that they have for the rover before they send them up to Perseverance on the surface of Mars.  Also, if they have a problem with Perseverance it gives them a place to practice how they recover from that problem.  

Personally, for me, I would not like to become an astrobiologist.  I like science but not that much.  I like the simple questions of why and how does it work.  I’m not entirely sure that we as humans are meant to be on any other planet except earth.  Earth has been here for many many years and seems to reset itself.  I don’t care why and will never know why in my lifetime.  I’s just not something that I like to considerate doing as a career.

NASA is targeting no earlier than April 8 for the Ingenuity Mars Helicopter to make the first attempt at powered, controlled flight of an aircraft on another planet. Before the 4-pound (1.8-kilogram) rotorcraft can attempt its first flight, however, both it and its team must meet a series of daunting milestones.

Ingenuity remains attached to the belly of NASA’s Perseverance rover, which touched down on Mars Feb. 18. On March 21, the rover deployed the guitar case-shaped graphite composite debris shield that protected Ingenuity during landing. Ingenuity is battery powered and completely sef recharging from the solar panel on the top.  The rover currently is in transit to the “airfield” where Ingenuity will attempt to fly. Once deployed, Ingenuity will have 30 Martian days, or sols, (31 Earth days) to conduct its test flight campaign.  All data and pictures will  be transmitted to Perseverance and then uploaded for all to see.

Answer:

Due to environmental conditions.

Explanation:

With the passage of time, environmental conditions change which causes the evolution of of four legged land animals from fish like creature. This change occurs due to change in environment. In water, there is no need for legs because fish moves with the help of fins and tail but the organisms that lives on land has legs in order to move from one place to another so we can say that change in the physical structure of organism occurs due to environment.
