Answer:
We are only given one leaf, but the leaves in layer D of the same species would not be identical. Some of them could have deeper indentations or fewer indentations. A wider leaf surface area lets a plant absorb more sunlight, so it would be an advantage if leaves have fewer indentations.
The plants with fewer indentations will reproduce more, passing on their genes for fewer indentations. This repeats for a long time, then plant leaves overall would only have very small indentations (like the leaf for layer B).
Explanation:
There are mutations and variations that make one organism different from another organism, even if they're the same species.
Natural selection is when the environment "chooses" the organisms that have an advantage in the environment to reproduce. Organisms that are selected to reproduce can pass on their genes to future generations.
The deep indentation leaves from layer D were basically "phased out".
Suppose an individual giraffe could not reach high leaves on a tree
its neck was too short. Lamarck's theory would suggest that the giraffe could
undergo physical changes that would lengthen its neck simply by stretching
to reach the branches. What experimental result would disprove this?

2.What is vegetative propagation
[tex]\huge\underline\bold\blue{ƛƝƧƜЄƦ}[/tex]
Budding - It is a type of asexual reproduction where in a daughter organism is formed from a small projection known as bud. it develops as an outgrowth due to the repeated cell division on the parent body. when fully grown it detects to grow into a new independent individual
For.eg. hydra
Vegetative Propagation - it is a type of axle plant reproduction in which new plans are obtained from a part of the parent plant. under favorable conditions various touch to take part in the type of reproduction.this is known as natural vegetative propagation where plants parts like root stem and leaves develop into new plants
the property of vegetative propagation is used in cutting tearing and grafting these are known as the method of artificial vegetative propagation. they are used for many plants like sugarcane , rose, etc

Answer:
The correct answer is - 0 m/s.
Explanation:
In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.
'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.
What, in general, can you infer about the energy per square meter at the equator?
Answer:
0-degrees latitude, at the equator. The temperatures would be higher because the radiation from the sun is more direct. The overall energy is greater per square meter because the sunlight is more direct.
What distinguishes each element from all others, and gives it unique physical and chemical properties?
The physical and chemical properties of each element distinguishes form all others elements, all these properties depends upon the number of protons present in an element. Thus, the correct option is D.
What are elements?A chemical element is a species of atoms which contain the same number of protons in the nucleus. Unlike the chemical compounds, elements present in the periodic table cannot be broken down into simpler substances by any chemical reaction.
The number of protons present in the nucleus is the defining property of the chemical element. It is referred to as the atomic number, is represented by the symbol (Z). All the atoms which have the same atomic number are the atoms of same element. All of the matter present in the universe is composed of chemical elements.

Answer:
Water, carbon dioxide,oxygen and some other substances can pass through the cell membrane because oxygen and carbon dioxide moves across the cell membranes from a simple diffusion a process that does not require any energy input and is driven by differences in concentration on the other side of the cell membrane.
There are two bright stars in a constellation. One of the stars appears red and the other star appears blue. Which of the following is the best explanation for the difference in the stars' color?
The blue star must be moving toward Earth and the red star away from Earth.
The red star must be moving toward Earth and the blue star away from Earth.
The red star must have a greater surface temperature compared to the blue star.
The blue star must have a greater surface temperature compared to the red star.
Given what we know, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.
How do we explain this?This has to do with a phenomenon known as the doppler effect. This effect explains how we can perceive a star as red or blue depending on its distance and on whether or not it's moving towards or away from us. When an object moves away from us, the wavelengths of the light it emits are stretched, making the object appear red. However, when it moves towards us, this increases the wave frequency that reaches us and we observe it as blue.
Therefore, we can confirm that the explanation for the situation described is that the blue star must be moving toward Earth and the red star away from Earth.

Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had.
Passage
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.
Answer:
It decreases cost of production on the crop as well as increase production.
Explanation:
It is a very efficient method to save a corn plant from the attack of bacteria. This method is used in almost each and every plant in order to make it resistance against harmful pests and microorganism. By using this technology, the cost of production on the growing of crop decreases which gives more profit to the farmers as well increase the overall productivity of that corn crop.
Answer:
One of the ways we have influenced the traits in corn is through selective breeding. We now have taller plants, and bigger ears of corn, that taste better. Another way we have influenced the traits is by modifying them to be pest resistant.

a particle of oxygen has 8 protons and 8 electrons. is this an atom or an ion? what's the charge?
Answer: It is Atom and the charge would be postive.
Explanation: If the atom had 8 protons and 8 electrons (oxygen for example), knocking one of the electrons out, makes 8 protons and 7 electrons. The atom now has a net charge of +1 because the 7 electrons cancil the positive charges of 7 of the protons in the nucleus, but there is one remaining proton with a positive charge.Oxygen's 8 electrons are negatively charged, and they orbit the atomic nucleus and balance the positive charge of the 8 protons. The positive charge of 1 proton exactly cancels the negative charge of 1 electron. Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
Hope this helps :) Can u plz mark me branliest :)
A particle of oxygen has 8 protons and 8 electrons in an atom and the charge on it is zero.
What is an atom?It is the smallest particle of matter composed of electrons and a nucleus of protons and neutrons.
What is an ion?It is an atom with a positive or negative charge due to either loss or gain of electrons.
Every atom tends to have a noble gas configuration for stability and they either tend to lose, gain, or share electrons to achieve it.
The oxygen atom generally gains 2 electrons to complete its octet and has a net -2 charge.

If the length of the small intestine is ( 6 ) meters and the length of the large intestine ( 1.5 ) meters. what is the ratio of the large intestine to the small intestine
Answer:
1:4
Explanation:
According to the information provided in this question, the length of the small intestine is 6 meters and the length of the large intestine 1.5 meters. This means that the small intestine is longer than the large intestine.
To find the ratio of large intestine to the small intestine, we divide each length value by the smallest (1.5) i.e.
Large intestine = 1.5 ÷ 1.5 = 1
Small intestine = 6 ÷ 1.5 = 4
The ratio of large to small intestine according to this question is 1:4
