22. What is a beneficial way ethylene affects plants; what is a negative way ?

Answers

Answer 1

Answer:

Beneficial is fruit ripening

And negative is abscission.

Explanation:

Ethylene is a plant growth regulator or phytohormone of plant. It is beneficial to plants in that it aid fruit ripening, it hasten flower opening and shedding of leaves.

Ethylene also have a negative effect and they include; Ethylene effects include: it result in loss of chlorophyll, abortion of major plants part, it lead to the stem shortening, abscission or dropping of plant parts, epinasty, and dormancy and scinence. Thus hormone can be produced when plants are injured, either mechanically or are affect by certain disease

How was early Earth's atmosphere different from today's atmosphere?​

Answers

Answer:

The early Earth was very different from our Earth today.

Explanation:

Earth's first atmosphere had lots of water vapor but had almost no oxygen. Later, frequent volcanic eruptions put several different gases into the air (Figure 12.13). These gases created a new type of atmosphere for Earth.

Answer:

The atmosphere we enjoy today is radically different from the atmosphere that formed with the Earth billions of years ago. ... As the Earth cooled enough to form a solid crust (4.4 billion years ago), it was covered with active volcanos. These volcanos spewed out gasses, like water vapor, carbon dioxide and ammonia.

How has the Earth's atmosphere changed over time?

Water vapor, carbon dioxide, methane, ammonia, and other gases similar to the ones produced by volcanoes today were expelled. Over a vast amount of time, millions of years, the earth gradually cooled. ... From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

The cell theory is a scientific explanation about the characteristics of cells in living things discovery of cells occurred in the 1600s which piece of equipment my students in science class used to investigate the cell theory

Answers

Answer:

Then, what is the question????

In 1665, Robert Hooke, a scientist published Micrographia, a book full of illustrations and descriptions of organisms observed under the recently invented microscope, hence Hooke's discovery of the cell was successful with the invention of the microscope.

What is Microscope?

A microscope is defined as a laboratory instrument used to examine objects that are too small to be seen by the uncovered eye. Microscopy is the science of examining small objects and structures using a microscope. The word microscopic means invisible to the eye unless aided by a microscope.

Without the microscope, we would not know about the existence of cells or how plants breathe or how rocks change over time. Cell theory was discovered by Robert Hooke in 1665 with the help of a microscope.

The question 'is the level of genetic variation in the gametes related to the amount of DNA methylation observed?' is the MOST appropriate question raised by this observation.

Epigenetics refers to all changes in gene expression that are not associated with the DNA (nucleotide) sequence.

Epigenetic modifications include DNA methylation, histone modifications (e.g., acetylation methylation, etc) and regulatory non-coding RNA pathways.

The variation in the DNA methylation pattern may be associated with suppression (or activation) of gene expression.

Look at the symbiotic relationships listed below and select all where at least one organism is harmed (the reading calls these harmful relationships). Group of answer choices Commensalism Parasitism Mutualism Predator-Prey Competition

Answers

Answer: Parasitism, Predator-Prey, Competition

Explanation:

The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.

Why can information only pass in one direction across synapse?? pls help !!

Answers

A Nerve electrical impulse only travels in one direction. There are several reasons nerve impulses only travel in one direction. The most important is synaptic transport.
In order for a "nerve impulse" to pass from cell to cell, it must cross synaptic junctions. The nerve cells are lined up head to tail all the way down a nerve track, and are not connected, but have tiny gaps between them and the next cell. These tiny gaps are called synapses.
When you get a nerve firing, you have probably heard that it is an electrical impulse that carries the signal. This is true, but it is not electrical in the same way your wall outlet works. This is electrochemical energy. Neurotransmitters are molecules that fit like a lock and key into a specific receptor. The receptor is located on the next cell in the line. When the neurotransmitter hits the receptor on the next cell in line, it signals that cell to begin a firing as well.
This will continue all the way down the length of the nerve track. In a nutshell, a nerve firing results in a chain reaction down the nerve cell's axon, or stemlike section. Sodium (Na+) ions flow in, potassium (K+) ions flow out, and we get an electrochemical gradient flowing down the length of the cell. You can think of it as a line of gunpowder that someone lit, with the flame traveling down the length of it. Common electrical power is more like a hose full of water, and when you put pressure on one end, the water shoots out the other.
Therefore, nerve impulses cannot travel in the opposite direction, because nerve cells only have neurotransmitter storage vesicles going one way, and receptors in one place.

Does natural selection affect humans? How and why

Answers

Answer:

Yes it does affect humans.

Explanation:

Natural selection acts on the phenotype, but evolution is a change in the frequency of alleles in a population over time, a change in genotype. So natural selection acts on phenotype, but it is the connection to genotype that makes it the mechanism of evolution. Many traits vary among different members of a population of humans and animals, from body size to hair color, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. In scientific terms, these hazards are referred to as selection pressures. They put pressure on us to adapt in order to survive the environment we are in and reproduce. It is selection pressure that drives natural selection "survival of the fittest" and it is how we evolved into the species we are today.
