How does rhizopus reproduce

Answers

Answer 1

Rhizopus species grow as filamentous, branching hyphae that generally lack cross-walls (i.e., they are coenocytic). They reproduce by forming asexual and sexual spores. ... In sexual reproduction, a dark zygospore is produced at the point where two compatible mycelia fuse.

Explanation:

up to about three thousand million years ago there was no oxygen in Earth's atmosphere today about one-fifth of the atmosphere is oxygen gas. suggest what caused this change???


pls help​

Answers

Answer:

Oxygen makes up about one-fifth the volume of Earth'­s atmosphere today, and is a central element of life as we know it.

But that wasn'­t always the case. Oxygen, although always present in compounds in Earth'­s interior, atmosphere, and oceans, did not begin to accumulate in the atmosphere as oxygen gas (O2) until well into the planet'­s history. What the atmosphere was like prior to oxygen'­s rise is a puzzle that Earth scientists have only begun to piece together.

Earth coalesced a little more than 4.5 billion years ago from bits of cosmic debris. Liquid oceans existed on the planet almost from the beginning, although in all likelihood they were repeatedly vaporized by the massive meteorites that regularly clobbered the planet during its first 700 million years of existence. Things had settled down by 3.8 billion years ago, when the first rocks that formed under water appear in the geologic record. (They exist in what is now southwest Greenland.)

If Earth had water, it must have had an atmosphere, and if it had an atmosphere, it must have had a climate. What was Earth'­s early atmosphere made of? Nitrogen (N2), certainly. Nitrogen makes up the bulk of today'­s atmosphere and likely has been around since the beginning. Water vapor (H2O), probably from volcanic emissions. Carbon dioxide (CO2), also emitted by volcanic eruptions, which were plentiful at that time. And methane (CH4), generated inside the Earth and possibly also by methane-producing microbes that thrived on and in the seafloor, as they do today.

Carbon dioxide, water vapor, and methane played an important role in Earth'­s subsequent development. Four billion years ago, the Sun was 30 percent dimmer, and therefore colder, than it is today. Under such conditions, Earth'­s water should have been frozen, yet clearly it wasn'­t. The water vapor, carbon dioxide, and methane acted as greenhouse gases, trapping heat and insulating the early Earth during a critical period in its development.

Of oxygen, meanwhile, the early atmosphere held barely a trace. What did exist likely formed when solar radiation split airborne molecules of water (H2O) into hydrogen (H2) and oxygen (O2). Hydrogen, a lightweight gas, would have risen above the atmosphere and slowly been lost to space. The heavier oxygen gas, left behind, would have quickly reacted with atmospheric gases such as methane or with minerals on Earth'­s surface and been drawn out of the atmosphere and back into the crust and mantle. Oxygen could only begin to accumulate in the atmosphere if it was being produced faster than it was being removed'—in other words, if something else was also producing it.

That something was life. Although the fossil evidence is sketchy, methane-producing microbes may have inhabited Earth as long ago as 3.8 billion years. By 2.7 billion years ago, a new kind of life had established itself: photosynthetic microbes called cyanobacteria, which were capable of using the Sun'­s energy to convert carbon dioxide and water into food with oxygen gas as a waste product. They lived in shallow seas, protected from full exposure to the Sun'­s harmful radiation. (To learn more about these organisms and the fossil evidence for them, watch the accompanying video "Early Fossil Life.")

How has the poison changed the concentration of pyruvate, NADH and intermembrane H+ in Jared’s cells?

Answers

Answer:

no change,  increase, decrease

Explanation:

I just did it

Cyanide interrupts the electron transporter chain. Pyruvate concentration DOES NOT CHANGE. NADH concentration INCREASES in the matrix, and H+ concentration DECREASES in the intermembrane space.

-----------------------------------

Let us firts make a quick revision of aerobic respiration.

Through cellular respiration, cells degrade organic compounds and produce energy.

Aerobic respiration takes place in three steps:

1)  Glycolysis is the first step of cellular respiration. It occurs in the cytoplasm, and its final product is Pyruvate.

2) The Krebs cycle takes place in the mitochondria matrix.

3) The electron transporter chain is placed in the internal mitochondrial membrane.

                                           

                                              *******************

We already know that cyanide affects the electron transporter chain. So, let us focus on its functioning under normal conditions and under the cyanide effect.

⇒  Under normal conditions,

ATP is produced at the end of the electron transporter chain.

• The electron transporter chain constitutes a series of enzymatic reactions to release and save energy for the correct functioning of the organism.

• Along the chain, there are four proteinic complexes in the membrane, I, II, III, and IV, that contain the electrons transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.

Cytochrome oxidase (P450) is one of the enzymes involved in this electron transport.

NADH and FADH2 provide electrons to the chain.

• While electrons move along the chain, complexes I, III, and IV pump protons to the intermembrane space.

• At the end of the chain, water molecules and ATP are produced.  

⇒  Under cyanide effect,

• Ion cyanide inhibits cellular respiration.

• Cyanide binds to the ferric ion of cytochrome oxidase.

Cyanide-ferric binding inactivates the enzyme and blocks electron transference.

• The chain is interrupted. Hence,

NADH and FADH2 stop providing electrons, complexes I, II, and IV stop pumping protons to the intermembrane space, there is no oxygen consumption and no ATP production.

• Since muscles do not get to have ATP as a source of energy, they weaken.

• The interruption of the electron transporter chain produces an anaerobic state that could be culminating.

                                        *************************

Now, let us answer the question

Pyruvate concentration  ⇒ NO CHANGE

Since Pyruvate is produced in the cytoplasm, it is not affected by cyanide. Remember that cyanide only affects the electron transporter chain.

NADH concentration ⇒ INCREASE

Since NADH provides electrons to the chain, and Cyanide interrupts electron transport, there is an accumulation of NADH molecules in the matrix.

Intermembrane H+ concentration ⇒ DECREASE

Since the electron transporter chain is interrupted, no electrons are being carried, and no protons are being pumped to the intermembrane space.

What would most likely happen to a person who is not getting enough essential amino acids in his or her diet?

The body would synthesize the amino acids.
Muscle growth and repair would be limited.
Stored protein would break down.
The formation of proteins would increase.

Answers

Answer:

Muscle growth and repair would be limited

Explanation:

plz give me brainiest

Essential amino acids are the vital nutrients required by the body. The deficiency of the amino acids in the diet will limit the growth and repair of the muscles. Thus, option B is correct.

What are the essential amino acids?

Essential amino acids are the amino acids that are not synthesized by the body and instead are taken from external sources in the diet. Some of the essential amino acids include histidine, lysine, valine, phenylalanine, etc.

The essential amino acids improve the musculoskeletal and the immune system along with stimulating the growth and production of hormones.

If the diet lacks the essential amino acids then the repair mechanism and the growth of the body will be limited as they are not synthesized by the body.

Therefore, the absence of essential amino acids limits muscular growth and repair.

Using renewable energy will always be better than fossil fuels.

This is because fossil fuels need a very long time to renew themselves. And we will run out of them long before they can renew themselves. Besides this, there is a more concerning and very alarming issue with using fossil fuels instead of other energy sources. Global warming and environmental destruction is a very big problem for us in the 21st century. The air is more and more polluted. Temperatures are rising and oceans are rising with them.

Answer:

The species of Archaeopteryx is lithographica and siemensii

Explanation:

Fun fact: Archaeopteryx is a combination of two ancient Greek words: archaīos, meaning "ancient," and ptéryx, meaning "feather" or "wing." 

Archaeopteryx has long been thought to be the earliest known bird and a transitional form between birds and reptiles.

What are Archaeopteryx?

Many consider Archaeopteryx, which lived approximately 150 million years ago, to be the first bird.

It is actually a transitional species between the birds we see in our backyards and predatory dinosaurs like Deinonychus.

Many features of Archaeopteryx, such as teeth and a long tail, indicate that it evolved from comparatively tiny carnivorous dinosaurs.

It also has a wishbone, a breastbone, hollow thin-walled bones, air sacs in the backbones, and feathers, as do nonavian coelurosaurian relatives of birds.

Archaeopteryx was thought to be the first recognized bird and a transitional form between birds and reptiles for a long time.

Thus, the two groups that are represented in archaeopteryx are birds and reptiles.
