Answer: All angiosperms are comprised of stamens which are the reproductive structures of the flowers. They produce the pollen grains that carry the hereditary information. The carpels enclose developing seeds that may turn into a fruit. The production of the endosperm is one of the greatest advantages of angiosperms.

the gametophyte stage and the sporophyte stage are the first 2 stages of a plants life.
Explanation:
The plants go through haploid and diploid stages during their life cycle.
What is the alternation of generation?Plants have two distinct multicellular stages in their life cycle diploid and haploid.
In the diploid stage, the plant has 2 sets of chromosomes while in the haploid stage the plant only single set of chromosomes.

From point W to point Z, the ball is B- Potential energy was transformed to kinetic energy. We know this because, at point W, the ball is in its potential form, it has the potential to roll but it has not yet started to. As we let the ball go, we turn that potential energy into kinetic energy, which is the energy that it has due to its motion.

combination that is the result?
Atom
Compound
Element
Consideting the definition of compound, the correct answer is second option: Carbon, hydrogen and chlorine atoms combine chemically, forming compounds.
A compound is any substance formed by the union of two or more types of chemical elements, linked together by chemical bonds.
In other words, A chemical compound is the substance that results from the combination of two or more different chemical elements linked under a certain arrangement and in certain proportions.
Each compound has a chemical name (which responds to certain nomenclature rules) and a formula that indicates the elements it is composed of and the number of atoms each contains.
Then, the correct answer is second option: Carbon, hydrogen and chlorine atoms combine chemically, forming compounds.

what is the primary pigment that makes leaves green in land plants?
Chlorophyll is the primary pigment that makes leaves green in land plants, by absorbing red and blue light.
What is chlorophyll?It is a pigment present in the plant leaves, through which plant leaves apers green in observation, it plays several roles in the plants other than the green appearance of the leaves.
During photosynthesis, this chlorophyll pigment is responsible to form reaction center through which light is absorbed and leads to a process through which light converts into chemical energy for the synthesis of food.
It is present in the chloroplast, which is the site of photosynthesis, and provides the necessary components for plant food synthesis.
Therefore, the primary pigment that makes leaves green in land plants is known as chlorophyll.

TRANSCRIPTION AND TRANSLATION
Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation.
Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA.
The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.
DNA → RNA → Protein
DNA and RNA are similar molecules and are both built from smaller molecules called nucleotides. Proteins are made from a sequence of amino acids rather than nucleotides. Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein.
These two processes are essential for life. They are found in all organisms – eukaryotic and prokaryotic. Converting genetic information into proteins has kept life in existence for billions of years.
DNA and RNA
RNA and DNA are very similar molecules. They are both nucleic acids (one of the four molecules of life), they are both built on a foundation of nucleotides and they both contain four nitrogenous bases that pair up.
A strand of DNA contains a chain of connecting nucleotides. Each nucleotide contains a sugar, and a nitrogenous base and a phosphate group. There is a total of four different nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).
A strand of DNA is almost always found bonded to another strand of DNA in a double helix. Two strands of DNA are bonded together by their nitrogenous bases. The bases form what are called ‘base pairs’ where adenine and thymine bond together and guanine and cytosine bond together.
Adenine and thymine are complementary bases and do not bond with the guanine and cytosine. Guanine and cytosine only bond with each other and not adenine or thymine.
There are a couple of key differences between the structure of DNA and RNA molecules. They contain different sugars. DNA has a deoxyribose sugar while RNA has a ribose sugar.

Answer:
Do you think there is a quantitative relationship between transpiration rate and number or size of leaves on the stem? Explain your answer. Yes, the more leaves a plant has, means more stomata will be available for transpiration. ... Without light to facilitate photosynthesis, most plants close their stomata at night.

Organize these rock layer from youngest to oldest
Breccia
Conglomerate
Dolostone
Shale
From youngest to oldest are Breccia, Conglomerate, Dolostone, and Shale, and as per geology, the principle of superposition states that in a sequence of layered rocks, the youngest layer is on top and the oldest layer is at the bottom.
What are rock layers?Breccia is the youngest layer in the sequence. Breccia is a coarse-grained sedimentary rock made up of angular fragments of other rocks that have been cemented together. It is formed through a process called brecciation. Conglomerate is also a coarse-grained sedimentary rock, but unlike breccia, its fragments are rounded and well-worn, indicating that they have been transported over a distance by water or wind before being deposited and cemented, and dolostone is older than both breccia and conglomerate. Shale is the oldest layer in the sequence.
Hence, From youngest to oldest are Breccia, Conglomerate, Dolostone, and Shale.

The chemiosmotic hypothesis states that the energy for the production of ATP during photosynthesis comes from the Mitochondria.
The mitochondria is regarded as very important and the power(energy) house of the cell as a lot of ATP synthesis activities takes place in this organelle.
The hypothesis was used to prove that most of the ATP production that takes place in respiring cells comes from the electrochemical gradient present across the inner membranes of mitochondria.
ATP is formed from the break down of the molecules rich in energy such as glucose and the use of energy of NADH and FADH₂ which are formed from its breakdown.

What type of diffusion is aided with a transport protein?
a. Osmosis
b. Permeated diffusion
c. Facilitated diffusion
d. Osmotic diffusion
Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Facilitated diffusion is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient.
