Bananas are curved why?
Explanation:
The reason why bananas are curved is due to a process called negative geotropism. So, initially bananas start by growing towards the ground, but will eventually start growing towards the sun. With that being said, you’ll often find that some bananas are completely straight. did it help
Answer: Negative geotropism
Explanation: The reason why bananas are curved is due to a process called negative geotropism. So, initially bananas start by growing towards the ground, but will eventually start growing towards the sun. With that being said, you’ll often find that some bananas are completely straight. This is because of an innovation known as bagging, whereby the fruit is covered in order to protect it from insects and animals.
Integral proteins are mostly involved in enzymatic function.
transport function. receptors. recognition sites.
Option 2 is Correct. In primary active transport, carrier proteins are used, but in secondary active transport, channel proteins are used.
In contrast to secondary active transport, which can move two substances at once, primary active transport can only move one chemical at a time. The two molecules moving in secondary active transport may do so in different directions or in the same direction (both into the cell) (i.e., one into and one out of the cell).
Membrane transport proteins can be divided into two groups: carriers and channels. Across the lipid bilayer, both create continuous protein routes. Solute flow through channel proteins is always passive, in contrast to the active or passive nature of transport by carriers.

How many atoms are in 1 mole of H2O?
The number of atoms in 1 mole of H₂O is 6.02 × 10²³ particles.
The number of atomic particles of an element or compound depends on the number of moles of that element or compound.
By definition, 1 mole of a substance has a total of 6.02 × 10²³ particles, where this number is called Avogadro's number.
In this case, the substance is water (H₂O). So that 1 mole has as many particles as:
Number of particles = 1 x 6.02 × 10²³
Number of particles = 16.02 × 10²³ particles

How do ecologists define the term ecosystem? what makes up an ecosystem?
An ecosystem is a region where a bubble of life is created by plants, animals, and other species interacting with the weather, environment, and other factors,is defined by ecologists,
Ecosystems are made up of both biotic, or living, and abiotic, or nonliving, components. Plants, animals, and other species are biotic factors.An ecosystem's productivity, or how much is produced and how quickly it returns, as well as its biomass or the total weight of living things in the ecosystem can all be used to measure it.

What do you call to a process released by animals which is carbon dioxide?
The process by which carbon dioxide is released by animals is called respiration.
Cellular respiration is another aspect of respiration. Carbon dioxide and water vapor are gases that all plants and animals release back into the atmosphere. For a cell to produce the energy it requires, it must breathe. Cellular respiration is the term for this process. By mixing glucose with oxygen from the air, organisms create energy during the process of respiration. Glucose and oxygen are converted into energy and carbon dioxide during cellular respiration. Therefore, during the process of cellular respiration, carbon dioxide is released into the atmosphere.

Someone who is walking or running has kinetic energy in it. Kinetic energy is the energy possessed by an object because of its motion or the energy in moving objects.
Speed of walking = Vw
Speed of roading bike = Vb
Given Vb = 3Vw
The power used in both cases is the same to cover the distance.
So, Pw = Pb
Energy used while walking = Ew
Energy used while roading bike = Eb
Force while walking = Fw = Ew/d

In metabolic reactions mediated by enzymes, the substrates turn into products faster than they would naturally do.
Enzymes act as catalyzer molecules to accelerate natural reactions.
There are two main types of metabolic reactions mediated by enzymes,
AnabolismCatabolism
Catabolism is the process through which a large molecule is broken into simpler smaller molecules. The enzyme gets in contact with the substrate and breaks it apart into pieces.
Enzymes have specific active sites to which the substrate binds.
Once these large molecules join through these binding sites, they compose the enzyme-substrate complex.
The enzyme turns the substrate into smaller product molecules.
Finally, these smaller molecules are released into the environment.
In the image, we can see this sequence of events.
1) The large molecule is H₂O₂ that binds catalase by its active site.
2) Both of them together compose the H₂O₂-catalase complex (enzyme-substrate complex).
3) Catalaze breaks down H₂O₂ producing H₂O and O₂.

A dna mutation changes the shape of the extracellulara. Trueb. False
b. False
DNA mutations occur in the genetic material of an organism, specifically in the DNA sequence. The shape of the extracellular portion of a protein is determined by the amino acid sequence of the protein, which is encoded by the DNA. A change in the DNA sequence can result in a change in the amino acid sequence and therefore the shape of the protein, but the mutation would be located in the DNA, not in the extracellular portion of the protein.
It's important to note that a change in the shape of extracellular portion of a protein, can have various effects on the protein activity, stability, and interactions with other molecules, but the change would occur after the protein is translated from the DNA, not in the DNA itself.
