Answer:
True, nitrogen fixation converts atmospheric nitrogen into nitrogen that can be used by plants.
Explanation:
Think about water. There's plenty of water on Earth, but very few is actually drinkable, at least for humans. So we have to fix it by filtering out dangerous bacteria in the water and other dangerous stuff before being able to actually drink it. Same with atmospheric nitrogen. It must be "fixed" before plants can actually use them.

How do mitochondria differ from chloroplast
Explanation:
Mitochondria and chloroplast are organelles found in a plant cell. However, chloroplast is absent in an animal but mitochondria is found in both.
Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients while Chloroplast is the site for photosynthesis in a plant cell.
Answer:
MitochondriaKnown as the powerhouse of the cell, it is responsible for energy metabolism and cellular respiration.chloroplastLarger and much more complex than a mitochondrion, it is the site where photosynthesis takes place.Hope this helps you ❤️MaRk me as brainliest ❤️^_^do fertilised eggs divide to form a foetus
Answer:
yes
Explanation:
the chromosome number of the egg and and sperm are halved ,and are then joined together. the fusion of the the nucleus of the haploid male gamete with the haploid female gamete is referred to as fertization and the product of fertilization is zygote.
The diploid single zygote then divides repeatedly and develops to produce the offspring whose somatic cells are diploid.The zygote is the initial stage in baby development. It is also known as a fertilized ovum formed from the union of the sperm cell and the egg cell. Foetus refers to the final stage in baby development.
define the term excretion.
state an excretory product that is passed out trough the lungs.
outline the role of the liver in excretion.
Answer:
Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin.
Carbon dioxide
The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic.

I hope this will help you if not then sorry, have a great day :)Which of the following is the correct Lewis structure diagram for Sodium (Na)? (2 points)
Select one:
a. The letters Na with one dot
b. The letters Na with two dots
c. The letters Na with three dots
d. The letters Na with four dots
Answer:
a. The letters Na with one dot
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.
Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.
Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.
A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.
Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.
For example, the Lewis structure diagram for Sodium (Na) is •Na.
Answer:
Na with 1 dot

What adaptations did Charles Darwin notice in the finches of the Galapagos Islands that helped him develop his theory of evolution by natural selection?
A. All of the finches looked the same regardless of the island from which they came.
B. The finches had the same beak sizes and shapes as the mainland finches.
C. The finches had gone extinct from the islands due to volcanic activity.
D. The finches had beaks of different sizes and shapes that were suited to the available food.
Answer:
the answer is D
Explanation:
hope this helps:)
Charles Darwin noticed that the finches had beaks of different sizes and shapes that were suited to the available food. Option D is correct.
Changes in their beak size and shape have allowed them to adapt to different food sources: seed, insect, cactus flower and fruit, or even bird’s blood. Adaptive radiation is a well-known feature of the Galapagos finches.
Darwin concluded that these differences allowed the finches to better adapt to the food in their specific habitat - thin sharp beaks where the birds feed on insects and grubs and large claw-like beaks where they feed on buds, fruits, and nuts.
So the correct option is D.

You are studying nuclear lamins and use recombinant DNA technology to alter the coding sequence of a nuclear lamin gene. The alteration you make creates a situation such that the gene now codes for a nuclear lamin protein that can no longer be phosphorylated when the nuclear envelope is broken down during mitosis. What do you predict would happen if the cell only had the altered nuclear lamin gene (and not the unaltered version)
Answer:
Nuclear lamins will no longer disassemble during mitosis
Explanation:
The nuclear lamina is a fibrillar network inside the nucleus of eukaryotic cells, between the inner nuclear membrane and the peripheral chromatin. Nuclear lamins (also called simply lamin proteins) are intermediate filament-type proteins and represent the major building blocks of the nuclear lamina. During mitosis, the nuclear lamina is disassembled by hyperphosphorylation of nuclear lamins and lamina-associated proteins. The protein responsible for phosphorylating nuclear lamins is p34cdc2, a protein kinase that has a key role in controlling cell cycle progression. In consequence, a mutant form of the nuclear lamin proteins that cannot be phosphorylated will no longer be able to disassemble during mitosis.

Determine if the process is an example of anabolism or catabolism. French fries are digested in the intestine, breaking them into smaller molecules A body builder exercises to build muscles through protein synthesis A child eats a milkshake, which provides her with energy Process Catabolism
Answer:
--> French fries are digested in the intestine, breaking them into smaller molecules.(Catabolic process)
--> A body builder exercises to build muscles through protein synthesis. (Anabolic process)
--> A child eats a milkshake, which provides her with energy (catabolic process).
Explanation:
CATABOLISM is the process by which living organisms break down large or complex molecules into smaller molecules with the release of energy for their own use. Foods that we consume contains different nutrients which includes carbohydrates, fats &oil, and protein. These nutrients are made available for our body cell use and maintenance through the process of catabolism. Through catabolic processes, these nutrients are broken down into its smaller constituents with the release of energy which is used immediately to power molecular machines that support cell, tissue, and organ function. The following are examples of a catabolic process as it involves breakdown:
--> French fries are digested in the intestine, breaking them into smaller molecules and
--> A child eats a milkshake, which provides her with energy
In contrast, anabolic process involves the building up larger molecules from smaller ones. It uses ATP molecules generated by catabolic reactions as a form of energy to create new molecules that form new cells and tissues, and revitalize organs. For example, muscles can be built from the synthesis of proteins. This is also called anabolic training.
French fries are digested in the intestine, breaking them into smaller molecules - Catabolic process
A body builder exercises to build muscles through protein synthesis - Anabolic process
A child eats a milkshake, which provides her with energy - Catabolic process
Catabolism can be defined as the break down of larger molecules into smaller ones in a series of metabolic pathways of which the energy produced undergoes oxidation and then is released or it is used in another reaction. Digestion is an example of a catabolic process i.e. French fries are digested in the intestine, breaking them into smaller molecules. A child eating a milkshake, which provides her with energy (energy is produced) is a catabolic process.
Anabolism involves the build up of molecules from smaller molecules usually needed for bodily functions. Protein synthesis is an anabolic process (buildup from small amino acids to large proteins. A body builder exercises to build muscles through protein synthesis is an example of anabolism

Explanation:
Prior to the industrial revolution in the mid-1800s, a species of moth had light-colored wings speckled with small black spots. This coloration camouflaged the moths resting on the birch trees growing in their native habitat, since birch bark has similar coloring. In the early 1900s, this changed as dark soot produced by industrial pollution coated birch trees such that the trees lost their speckled coloring. Years later, it was observed that the moths of this species had changed from being light and speckled to being solid black. Which is the most plausible reason for this change
Answer:
The dark colored moths were due to a genetic mutation, and were more than likely present before the Industrial Revolution. Their fitness was low because predators could easily see them on the light-colored trees. They would be eaten before they could reproduce and pass on their genetic mutation. After the trees became darkened by soot, the darker colored moths now had the survival advantage, able to "hide" from predators. The lighter colored moths became more visible to predators, and the advantage shifted. Now, the light colored moths were more visible to predators, were eaten, and didn't have the chance to reproduce. The darker moths with the mutation had the survival advantage, blending in with the soot-covered trees, and were able to reproduce at higher rates, passing the mutation on to later generations.
