plants experience _______ gravitropism when their stems move upward.
A. positive
B. negative
Answer:
Negative
Explanation:
Gravitropisms. Phototropism is a response to the stimulus of light, whereas gravitropism (also called geotropism) is a response to the stimulus of gravity . When the stem grows against the force of gravity (upwards), this is known as a negative gravitropism.
Answer:
negative
Explanation:
this is because negative gravitropism is when a plant grows away from gravity (like moving upwards). then, positive gravitropism is when the roots of a plant move grow downwards.

which statement correctly describes greenhouse gases in the atmosphere?
Answer: It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.
Explanation:
Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.
Which of the following might be an adaptation for a predator? AS SOON AS POSSIBLE NEED HELP PLS THX
Answer:
we need the answers
Explanation:
Answer:
Many predators have adaptations that help them survive in the wild. For example, the snake shown below has camoflauge coloring to look like its surroundings. This gives it the element of surprise when going to attack its prey. These adaptations help the predator in hunting for food. Predators have "weapons", or adaptations, that help them hunt and kill prey. Predators' three main "weapons" are teeth, claws, and jaws. The lion below has all 3 of these "weapons" or adaptations that are used for catching its prey. A lion has sharp claws for catching and grabbing hold prey such as a zebra, and strong jaws and teeth for biting and killing the zebra and for ripping off and chewing the meat.

Explain how scientists use geologic time to determine the age of landforms.
geologic time use the layer of Rock to describe relationship of events and their sequence chronological order over the history of Earth the layering is a result of the buildingup tiny beats of rocks sediments or Lava cooling at the surface of many years think think of it like a stock of pancakes-the bottom layer is the one that was placed first and therefore is the oldest. the sediments that create the layer of the earth as said one or top of the other
17. At the end of their biology unit, 7th grade students were asked to make a glossary of biological terms. Which student did the best job of defining the word "heredity"?
Answer:
The question is incomplete, I found a matching question online:
At the end of their biology unit, 7th grade students were asked to make a glossary of biological terms. Which student did the best job of defining the word "heredity"?
A) Kendall- Heredity is the study of chromosomes and the genes that they contain.
B) Carla- Heredity is the passing of genetic information contained in chromosomes from one generation to the next.
C) Joseph- Heredity is the study of human characteristics passed down from parent to offspring.
D) Devon- Heredity is the reason that tall parents will usually have tall children.
Answer:
The correct answer is:
Carla- Heredity is the passing of genetic information contained in chromosomes from one generation to the next. (B)
Explanation:
Heredity, also known as inheritance is the passing down of genetic traits and genetic information from parents to their offspring through reproduction (sexual or asexual), and this information is contained in DNA materials called chromosomes.
Carla's definition most appropriatly captures the context of genetics, while Kendall and Joseph rather defined "genetics", which is the study of heredity.
Devon did not give a definition, but rather an example.

How do you think that wearing personal protective equipment helps to protect us from contracting airborne diseases?
Answer:
Airborne transmission may occur if patient respiratory activity or medical procedures generate respiratory aerosols. These aerosols contain particles that may travel much longer distances and remain airborne longer, but their infective potential is uncertain. Contact, droplet and airborne transmission are each relevant during airway manoeuvres in infected patients, particularly during tracheal intubation.

What happens to the chromosomes when a cell divides to make a copy of itself?
Answer:
the cell copies or replicates its chromosomes and then splits the copied chromosomes equally to make sure each daughter cell has a full set.
Answer:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies or "replicates" it's chromosomes and then splits the copied chromosomes equally to make sure that each. daughter cell has a full set.

How many reactions that occur in kreb cycle transfer electrons from substrate to an electron acccepting enzyme
Answer:
Four reactions that occur in kreb cycle transfer electrons from substrate to an electron accepting enzyme.
Explanation:
There is four such a response in which electron is transported from substrate to electron-allowing enzyme. In three of those, NAD+ is decreased to NADH and in one FAD decreases to FADH2. The TCA cycle is likewise recognized as the Krebs cycle after the signature of English biochemist Hans Kreb who illustrated the pathway in the 1930s.
