Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant.

Answer: 1. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift. 2. But scientists were at a loss to explain why some pieces of crust move much faster than others. A new study suggests these tectonic plates control their own speed more than the mantle does. ... The velocities of these plates and the velocities of the boundaries between these plates vary significantly on Earth." 3. Divergent boundaries -- where new crust is generated as the plates pull away from each other.

Convergent boundaries -- where crust is destroyed as one plate dives under another.

Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

Explanation:

1) According to the diagram, divergence among mammals took place about 75 mya.

2) Scientists are able to determine common ancestors by studying molecular data.

3) Darwin's theory of evolution by natural selection states that animals change over long periods of time.

4) Scientists are closesly studing how genes reorganize themselves.

5) Some scientists, however, think new species evolve quickly.

6) Still, among scientists, the principles of natural selection remain unchanged and highlight how animals evolve.

7) The main tool for the study of evolution is careful observation of fossils and the anatomy of animals.

8) Scientists also study animal embryology.

9) What no one doubts is the wide diversity among organisms on Earth.

10) The divergence that took place among mammals helps us understand why whales and dolphins are mammals and not fish.

Answer:

These are the possible phenotypes of the offspring

Answer:

Step 1-Light Dependent. CO2 and H2O enter the leaf.

Step 2- Light Dependent. Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.

Step 3- Light Dependent. The electrons move down to enzymes.

Step 4-Light Dependent. Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

Step 5-Light independent. The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.

Answer:

D have a nice day:

well to this answer it will be the heaviest object that will fall the faster the crayon will fall much much faster than the other objects listed.

The items will all hit the ground at the same time as they have an equal force.

It should be noted that the law of conservation of energy applies in this case. In such a situation, the weight or mass of the object is inconsiderate.

In this case, since a book a pencil, a paper clip, and a crayon at the same height in the air, are dropped, they will hit the ground with the same force.

Therefore, they'll fall at the same time.

Answer:

The correct answer is - reef corals and other calcareous organisms.

Explanation:

Acidification of the ocean is the continuous uptake of carbon dioxide from the atmosphere and reducing the pH of the water of the ocean. The acidification and warmth due to increasing the carbon dioxide in water cause harmful effects on the life of all marine life.

It affects coral reefs and other calcareous organisms as well as other organisms. These calcareous organisms required more efficiency to repair their cells or have to thickening of layers to survive in  case of acidification of the ocean or to

Answer:

Apples : adenine

Trees : thymine

Cars : cytosine

Garages : guanine

Explanation:

The bases in DNA are adenine, thymine, guanine, and cytosine. It helps to remember the popular mnemonic, "apples in the tree," that helps you remember that A goes with T, and "car in the garage," so C goes with G, to understand how DNA bases pair. The bases in RNA are adenine, uracil, guanine, and cytosine.

Answer:

The action and reaction forces are reciprocal (opposite) on an object. The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward. The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.

Explanation:

Answer:

the force is push and the reaction is moving forward.

Answer:

A does the object contain ice

Explanation:

The BEST question that would confirm that the object is a comet is "Does the object contain ice?" Hence the correct option is A.

Comets are small, icy celestial bodies that originate from the Kuiper Belt and the Oort Cloud. As they approach the Sun, they heat up and release gas and dust in the form of a coma and a tail, which can be observed from Earth. Therefore, if the object contains ice, it is most likely a comet.

Meteoroids, on the other hand, are smaller rocks that travel through space, and asteroids are larger rocks that orbit the Sun between Mars and Jupiter. Neither meteoroids nor asteroids typically contain ice.

As for the other options, whether the object contains metals or how big it is does not provide enough information to determine whether it is a comet, asteroid, or meteoroid. And while the location of the object may provide some clues about its origin, it is not a definitive factor in determining whether it is a comet.

Regeneration.

Explanation:

Planarian can be cut into pieces, and each piece can regenerate into a complete organism. Cells at the location of the wound site proliferate to form a blastema that will differentiate into new tissues and regenerate the missing parts of the piece of the cut planaria.

Answer:

The cell was first discovered by Robert Hooke in 1665 using a microscope.

The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s.

Hooke had discovered plant cells -- more precisely, what Hooke saw were the cell walls in cork tissue. In fact, it was Hooke who coined the term "cells": the boxlike cells of cork reminded him of the cells of a monastery.

Answer:

1. Zacharias Janssen invented the microscope, while the first to describe cells was Robert Hooke

2. Robert Hooke was the first scientist to do so

Answer:

B

Explanation:

the equation for photosynthesis is:

carbon dioxide + water ---> glucose +oxygen

                                     (light)

The statement that correctly describes the process of photosynthesis is that chloroplasts use carbon dioxide, water, and sunlight to produce sugars and oxygen. The correct option is B.

Photosynthesis is the process of producing food, nutrition, and energy. It is done by plants and algae because only they contain chlorophyll. Those organisms containing chlorophyll can perform photosynthesis.

It is a chemical process and the process involves, carbon dioxide, water, and sunlight, and it produces sugar and oxygen as a byproduct. The oxygen is released, whereas the sugar gives the energy.

The process can be described as chloroplast absorbing the sunlight for plants, and the process can only occur in the presence of light or sunlight.

Thus, the correct option is B. The chloroplasts use carbon dioxide, water, and sunlight to produce sugars and oxygen.
