A.) Past observations made early in history
B.) Microscopes
C.) Telescopes and space probes
D.) both a and c

Answers

Answer:

D.) both a and c

Explanation:

Past observations made early in history as well as telescopes and space probes are very important in studying our universe and galaxies.

Space probes are increasingly gaining momentum as technological and scientific advancements are being made. Telescopes are used to see or picture objects that are very far away in space. Also, understanding the past records and historical data is essential for the study of the universe.

Microscopes are not used in galactic studies. They are only used to study the world of micro-organisms.

B. They increase the efficiency of chemical reactions.

C.They reduce the energy needed for a chemical reaction to occur.

D. One enzyme catalyzes many different reactions.

E. They are only needed for a few chemical reactions in cells.


F. They can catalyze the same reaction repeatedly.

Answers

Answer:

They are necessary for a chemical reaction to occur

They increase the efficiency of chemical reactions

Enzymes are proteins that act as biological catalysts by speeding up chemical reactions. Substrates are molecules with which enzymes can interact, and enzymes convert substrates into other molecules known as products.

What is enzymes? Biochemical reactions are sped up by enzymes, which operate as biological catalysts. The most popular explanation proposes that enzymes bind to the substrate molecule and create a transition state. An energy barrier that the substrates must pass separates the products from the substrates as the reaction progresses.Digressionary enzymes are produced by your pancreas, small intestine, and stomach. The "powerhouse" of digestion's enzymes is actually the pancreas. The most crucial digestive enzymes that break down proteins, carbs, and fats are produced by it.

Please explain in your own words how a nebula forms into a star, using the terms: Mass, Gravity, Pressure, Temperature, Nuclear Fusion.

Answers

Once massive stars reach the red giant phase, the core temperature continues to increase as carbon atoms are formed from the fusion of helium atoms. Gravity continues to pull together the carbon atoms in the core until the temperature reaches 600,000,000 degrees Celsius. At this temperature, carbon atoms form heavy elements such as oxygen and nitrogen. The fusion and production of heavy elements continues until iron starts to form. At this point, fusion stops and the iron atoms start to absorb energy. This energy is eventually released in a powerful explosion called a supernova. A supernova can light the sky up for weeks. The temperature in a supernova can reach 1,000,000,000 degrees Celsius. This high temperature can lead to the production of new elements which may appear in the new nebula that results after the supernova explosion. The core of a massive star that is 1.5 to 4 times as massive as our Sun ends up as a neutron star after the supernova. Neutron stars spin rapidly giving off radio waves. If the radio waves appear to be emitted in pulses (due to the star's spin), these neutron stars are called pulsars. The core of a massive star that has 10 or more times the mass of our Sun remains massive after the supernova. No nuclear fusion is taking place to support the core, so it is swallowed by its own gravity. It has now become a black hole which readily swallows any matter and energy that comes too near it. Some black holes have companion stars whose gases they pull off. As the gases are pulled down into the black hole, they heat up and give off energy in the form of X-rays. Black holes are detected by the X-rays which are given off as matter falls down into the hole.

What are 6 scientific facts about Spongilla lacustris?

Answers

Answer:

Physical characteristics: Freshwater sponges are crustlike, branched, or clumped. The texture is fragile and soft, and the color is whitish or green. Freshwater sponges have irregularly scattered and barely visible water-exit holes.

Geographic range: Freshwater sponges live in North America, Europe, and Asia.

Habitat: Freshwater sponges live in standing and running fresh water.

Diet: Freshwater sponges are filter feeders.

Behavior and reproduction: Scientists know little about how freshwater sponges behave. These sponges reproduce asexually by forming buds in late summer that spend the winter in a dormant state and emerge from the adult in the spring. Freshwater sponges reproduce sexually during the summer, giving birth to live larvae.

Explanation:

Answer:

Explanation:

1)spongilla belongs to phylum porifera

2)its whole body is covered with pores

3) they live in fresh water

4) respiration occur through whole body surface

5) extracellular and intracellular digestion occur

The same 600 N person lifts his 100 N carry-on bag upward a distance of 1.0 m. They travel another
10 m by riding on the "people mover." How much work was done in this situation?

Answers

Answer:

100J

Explanation:

The amount of work done here is 100J

Work done is the force applied along a particular distance.

 In this problem;

Weight of the object = 100N

Weight of the person  = 600N

Distance of raise  = 1m

Distance traveled  = 10m

Since work done is the force applied along a specific distance;

Work done  = force x distance  = 100 x 1  = 100J

In order to be able to make proteins, RNA has to migrate or travel to the cell cytoplasm.

Explanation:

RNA, specifically messenger RNA (mRNA) is responsible for carrying the genetic information needed for make proteins, so it must migrate from the cell nucleus to the cytoplasm.

DNA transcription and RNA synthesis, as well as maturation, occur in the cell nucleus. From there, the mRNA must travel to the cytoplasm to meet the ribosomes and initiate protein synthesis.
