why do sporangiophores grow vertically whereas rhizoids grow downwards​

Answers

Answer 1

Answer:

The sporangiophore grow vertically which is in an upward direction because it is positively phototrophic. This means that it grows towards the ray of light from the sun which is found above. This is usually due to the provision of solar(light) energy from the sun which is used for the photosynthetic processes of the plants

The rhizoides grow downwards because they are positively geotrophic. This means they grow according to the force of gravity which acts downwards.

what is maeant by sexual reproduction

Answers

Answer:

Sexual reproduction is a mode of reproduction involving the fusion of haploid female gamete (egg cell) and haploid male gamete (sperm cell). The fusion of these gametes occurs at fertilization resulting in the formation of a diploid zygote. ... Two major types of sexual reproduction are syngamy and conjugation.

Explanation:

Answer:

The production of a new living beings by intercourse of two different genes is called sexual reproduction.

Explanation:

In most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by the other (female).Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes combines with another to produce an organism composed of cells with two sets of chromosomes.

Predators need energy for cellular respiration but their
prey do not

by the predators to stay alive​

Answers

Answer:

Hi! The answer is Only some of the energy stored in the prey can be used by the predators to stay alive.

Explanation:

Predators are fewer in number than prey because they are higher up the food chain. In a food chain, an organism passes on only part of the energy it receives from food. With less energy, each level in a food chain supports fewer individuals than the one below it.

Help me guys please. What is a mutation? What causes mutation?​

Answers

Answer:

A mutation is a change in a DNA sequence. Mutations are commonly caused by mistakes during DNA replication. However, they can also be caused by ultraviolet radiation, exposure to chemicals called mutagens, and infection by viruses. But, a mutation usually occurs when a nucleotide in the DNA gets changed, causing the nucleotide sequence to be copied incorrectly which leads to the wrong code for a protein. This can sometimes be fatal.

Which tissue transmits signal to then brain?

Answers

Answer:

The Spinal Cord Transmits Signals to and from the Brain and Commands Reflexes The spinal cord is an elongated cylinder of neuron cell bodies, bundles of axons and other cells, protected by connective tissue and bone.

Explanation:

It connects to the brain at the medulla oblongata and runs down the vertebral column, the hollow tunnel enclosed within the vertebrae of the spine. The spinal cord is part of the central nervous system and serves as a kind of superhighway. Sensory information and motor commands travel up and down, heading to and from the brain. These signals speed in and out of the spinal cord via spinal nerves—the “on-ramps and off-ramps” that branch out to supply the limbs, torso, and pelvis. Some incoming signals demand a simple, immediate response. The spinal cord can shoot out a reflex command without bothering the brain.

A bacterial culture is being tested for its ability to reduce nitrate. After incubation and growth of the bacteria in nitrate broth, there is no accumulation of gas in the Durham tube. The test for the presence of nitrite is colorless. When zinc powder is added, a bright red color develops. Interpret these results.

Answers

Answer:

All this combination of reactions is summarized in that the bacteria reduced nitrate, that is, they added protons to said compound, giving nitrite as a product.

By promoting the appearance of nitrite and that it increases in its concentrations when the zinc dust is thrown away, it becomes reddish since there was a change in pH, that is, the medium was acidified.

Explanation:

Some bacteria take nitrate as a source and end up generating an oxide reduction reaction that gives nitrite as a product, if this reaction advances in a chain, that is, the nitrite is reduced after the nitrate, the product in the future would be ammonia

what is reproduction?​

Answers

Answer:

Reproduction is the biological process by which new individual organisms – "offspring" – are produced from their "parents".

Explanation:

You are comparing a reaction that produces a chemical change and one that produces a physical change. What evidence could you use to determine which type of change is occurring?

Answers

Answer:

There are no specified options in this question but the answer will be provided elaborately in order to fully comprehend it.

Please find the detailed answer in the explanation section.

Explanation:

Matter undergoes two types of changes viz: physical and chemical changes. A physical change, as the name suggests, involves a change in the physical nature of matter. A physical change does not change the chemical property of the substance involved. Since there is no chemical modification to the substance, no new substance is formed from a physical change. Hence, the substance only undergoes a change of state. For example, water (liquid) changing to ice (solid) is a physical change. Physical changes are usually reversibleb i.e. can be changed back to their previous form.

Chemical change is another type of change in which substances undergo a change in their chemical properties to form new substances. Changes like formation of gas bubbles, change in temperature, color change etc will be noticed during chemical changes. Examples of chemical changes are rusting, burning because they irreversibly change the chemical composition of the substances involved etc.

In a nutshell, in order to determine the type of change occuring in a reaction, one should look out for whether or not there is a change in nature of the substance leading to the formation or not of a new substance.

Answer:

Answer is in the Explanation Section

Explanation:

Either way, matter, physical and chemical changes are pretty much the same... Put it this way if you have a match and you light it what happens? If you said it burns your right! If not it is okay we all are not right. Because it is with the chemicals it's made with and adding oxygen makes it burn and breathe so it can burn freely.
