True or false: Guard cells close openings in the leaves slowing down water loss.
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.
Which is a natural source of greenhouse gases?
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 gasesThe greenhouse gases occur from natural sources and synthetic sources
Some of the natural sources of greenhouse gases are:
Respiration Decomposition of plants.Ocean release etc.Hence, a natural source of greenhouse gases is respiration

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?
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.

Adult stem cells are best described as?
Explanation:
1 Definition. Adult stem cells are undifferentiated cells that reside among differentiated cells in a tissue or organ. They have the ability to renew themselves and differentiate into specialized cell types.
Adult stem cells, also known as tissue-specific stem cells or somatic stem cells, are multipotent cells that replace damaged and dying cells.
What are somatic stem cells?Somatic stem cells, also known as adult stem cells, are found in organs and tissues, have the ability to self-renew and give rise to the differentiated cell types that make up that organ or tissue (multipotency), and play an important role in the maintenance and repair of those organs and tissues. Adult stem cells are sometimes referred to as embryonic stem cells.
The bone marrow, the skin, the intestine, the brain, the blood vessels, the teeth, the reproductive system, and the heart are only some of the organs and systems in the body that include somatic stem cells.

What would be an appropriate key for these traits
Answer:
The correct answer is -
TT - short BB - blue eyes
Tt - short tail Bb - blue eyes
tt - no tail bb - brown eyes
Explanation:
In this given question it is stated that short tails of ribbits are dominant over the no tail trait of the rabbits and similarly blue eyes trait of the rabbits is also dominant over the brown-eye trait.
A dominant trait is represented by a capital letter and a recessive trait is represented by the small letter so for the tails alleles will be denoted as T and t, and for the eyes, the alleles would be B for blue and b for brown.
The key for these traits would be-
TT - short BB - blue eyes, due to both dominant allele,
Tt - short tail Bb - blue eyes, due to dominant allele masks the recessive allele
tt - no tail bb - brown eyes, due to both alleles are recessive
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?
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.

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

What makes hunting breeds a good choice for studying dog navigation?
Answer: Pointers make an excellent choice for these excursions because they are lean and biddable—important qualities in dogs who will be hundreds of yards away from you during long-range hunts. Conversely, a dog plying the thick woods of a ruffed grouse covert will need to work close.
