Frida wants to measure the volume of a stone. The correct volume is B

The volume of the stone is 26 mL.

What is volume?

The initial volume = 473 mL

The final volume = 499 mL.

The final volume   − Initial volume

= 499 −  473

= 26 mL.

Therefore, Frida wants to measure the volume of a stone. The correct volume is B .The volume of the stone is 26 mL.

True or false: Guard cells close openings in the leaves slowing down water loss.

Answers

Answer:

True

Guard cells close openings in the leaves slowing down water loss.

Answer:

True

Explanation:

Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease. So when it is opened the water vapor depletes quicker but when its closed it slows down the process of depletion.

the diagram shows a model of how a hydra reproduces by budding​

Answers

Answer:

B. It shows offspring that have the same genes as the parent.

C. It shows asexual reproduction.

Explanation:

Hydra reproduces by budding​ which is kind of asexual reproduction. In budding, a small bud appears on the body of that organism and grow in size with the passage of time and finally detached from the parent body. so no fusion of gametes occurs so no chance of genetic variation. The offspring have the same genes as the parent because it forms from one parent.

Human p53 is a tumor-suppressor gene located on chromosome 17. The function of this gene is to prevent cells with damaged DNA from undergoing mitosis. What would most likely result if there were a mutation that decreased the function of the p53 gene?

Answers

The answer is “Germs cells would undergo only one meiotic division.

Explanation:

I remember learning this in my biology class

Single amino acid changes in p53 caused by TP53 gene mutations make the protein less functional. Without p53, cell proliferation is not efficiently controlled, and DNA damage can build up in cells.

How p53 gene is important?

Such cells might continue to divide uncontrollably, which would promote the development of tumors. By stopping the cell cycle to give the repair mechanisms time to restore genomic stability, p53 plays a significant function as a DNA repair facilitator.

Additionally, p53 adopted a variety of roles to directly influence the operation of different DNA-repair mechanisms.

Cancer cells may develop and spread throughout the body as a result of mutations (changes) in the p53 gene.

Therefore, numerous cancer kinds and the genetic disorder Li-Fraumeni syndrome have both been linked to these alterations.

Which is a natural source of greenhouse gases?

Answers

Answer:

Examples of greenhouses gases are water vapor, carbon dioxide. methane, nitrous oxide and ozone (O3). Lightning produces ozone as does UV light at high altitudes, methane is produced biologically and in volcanoes (but doesn’t last long in the atmosphere). Carbon Dioxide is also produced biologically and in volcanoes. Water vapour is most from ocean evaporation, which is bad news if the Earth gets hotter because that leads to more Water vapour.

Explanation:

A natural source of greenhouse gases is respiration

Greenhouse gases are gases that trap heat in the atmosphere and warm the planet. The major greenhouse gases are:

Carbon dioxideMethaneWater vapor Nitrous oxide Fluorinated gases

The greenhouse gases occur from natural sources and synthetic sources

Explain how the geologic time scale is used to organize Earth’s history.

Think about how the geologic time scale was created and how it is divided. Then answer the following questions.

How did scientists from the geologic time scale?
How is this scale organized?
What processes changed the Earth's environment during Precambrian time?

Answers

Answer:

The first principle you need to understand about geologic time is that the laws of nature are always the same. This means that the laws describing how things work are the same today as they were billions of years ago. For example, water freezes at 0°C. This law has always been true and always will be true. Knowing the natural laws helps you think about Earth’s past, because it gives you clues about how things happened very long ago. It means that we can use present-day processes to interpret the past. Imagine you find fossils of sea animals in a rock. The laws of nature say that sea animals must live in the sea. That law has never changed, so the rock must have formed near the sea. The rock may be millions of years old, but the fossils in it are a clue for us today about how it formed.

Now imagine that you find that same rock with fossils of a sea animal in a place that is very dry and nowhere near the sea. How could that be? Remember that the laws of nature never change. Therefore, the fossil means that the rock definitely formed by the sea. This tells you that even though the area is now dry, it must have once been underwater. Clues like this have helped scientists learn that Earth’s surface features have changed many times. Spots that were once covered by warm seas may now be cool and dry. Places that now have tall mountains may have once been low, flat ground. These kinds of changes take place over many millions of years, but they are still slowly going on today. The place where you live right now may look very different in the far future.

The first principle you need to understand about geologic time is that the laws of nature are always the same.

What is the Time scale?

Water, for instance, freezes at 0°C. This rule has held and will continue to hold forever.

Understanding natural principles facilitate historical thinking because it provides hints about how things were very long ago. It implies that we can interpret the past using current methods.

The rock must have formed close to the sea because this law has never changed.

Therefore, The first principle you need to understand about geologic time is that the laws of nature are always the same.

The air bubbles and spongy texture of bread are due to which process?
a. Lactic acid fermentation
b. Glycolysis
c. Alcoholic fermentation
d. The Krebs Cycle

Answers

Answer:alcoholic fermentation

Explanation:

The air bubbles and spongy texture of bread are a result of the process of baking of bread through alcoholic fermentation. Thus, the correct option is C.

What is Fermentation?

During fermentation, carbon dioxide is produced in cell and it is trapped as tiny pockets of air within the dough. The production of carbon dioxide causes the dough to rise.

During the baking of bread, carbon dioxide expands and causes the bread to rise further. In this process, alcohol is produced during fermentation which evaporates during the baking process of bread. In this process, yeast eats the sugar and releases carbon dioxide which causes air bubbles.

Therefore, the correct option is C.

In the Table of Elements, which SUBATOMIC particle of an Atom affects the arrangement of elements? *



Science

Answers

Answer:

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.
