Answer:
can lead to natural selection
Explanation:
Unequal reproductive success _can lead to natural selection_____.This is because if there is unequal reproductive success then one of the organisms is better suited for reproducing, surviving, and passing down their genes to their offspring rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where individuals better suited for their environment produce more and have better survivality.
So overtime, the organism which is weaker (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in a way "Nature selected" the better fit organism.

a) Name the structures that: i) Carry water and mineral salts to the leaf ii) Prevents too much water loss from the upper surface of the leaf iii) Opens to allow gases to pass into and out of the leaf iv) Is the site for most of the photosynthesis taking place v) Is the layer where light is able to pass through directly b) How does a leaf protect itself from unwanted intruders like bacteria from getting in and stopping important reactants from going out? PLEASE ANSWERR
Answer:
a) i) Xylem
ii) Upper epidermis
iii) Stoma
iv) Chroloplast
v) Palisade cell layer
b) By a waxy layer on the cuticle of the leaf
Explanation:
The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.
The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.

Describe under what conditions you might expect your cells to undergo anaerobic respiration. Be specific as to why these conditions would prevent normal cellular respiration to proceed. What product is produced under anaerobic conditions and is it harmful?
Answer:
Explanation:
Cells start undergoing anaerobic respiration when energy requirement is high and there is not sufficient availability of oxygen to produce required energy .
For example , when we we run fast , energy requirement by muscle cell is high but available oxygen level is not sufficient so cells start anaerobic respiration which produces lactic acid and this product creates tire-ness.
For normal respiration , oxygen is required . If there is lack of oxygen , aerobic respiration is not possible .
In yeast cells , alcohol is produced by anaerobic respiration. Alcohol is not harmful . In muscle cells , lactic acid is produced which is harmful .

Answer:c
Explanation:
A researcher interested in the disappearance of fallen leaves in a deciduous forest carried out a field experiment that lasted nearly a year. She collected all the leaves from 100 plots scattered throughout the forest. She measured the amount of leaves present in November, May and August. The percentages reflect the number of leaves found, using the November values as 100 percent.
Answer:
Elm: 50 %; 1 %
Hazel: 69 %; 4 %
Explanation:
Assume the table looked like this.
[tex]\begin{array}{crrr}\textbf{Month} & \textbf{Ash} & \textbf{Elm} &\textbf{Hazel}\\\text{Nov} &\text{4271 g}& \text{3481 g} & \text{1723 g}\\ & 100\, \% & 100\, \%&100\, \%\\\text{May} & \text{2431 g} & \text{1739 g} & \text{501 g}\\& 100\, \% & x \, \% &z \, \%\\ \text{Aug} & \text{1376 g} &\text{35 g} & \text{62 g}\\& 100\, \% & y \, \% & w \, \%\\\end{array}[/tex]
To get the percentages for each species for May and August, you divide that month's mass by the November mass and multiply by 100.
[tex]x = \dfrac{\text{1739 g}}{\text{3481 g}} \times 100 \, \% =50 \,\%\\\\y = \dfrac{\text{35 g}}{\text{3481 g}} \times 100 \, \% = 1 \,\%\\\\z = \dfrac{\text{501 g}}{\text{1723 g}} \times 100 \, \% = 69 \,\%\\\\w = \dfrac{\text{62 g}}{\text{1723 g}} \times 100 \, \% = 4 \,\%\\\\[/tex]
The figure below shows the graphs for ash and elm.
In an organism, X, it is found to be impossible to generate loss-of-function mutants for most genes. There is an alternative method of introducing random mutations that can later be screened for the gene(s) in question. This can be accomplished by using insertions due to what genetic entities?
Answer:
Transposable elements (TE)
Explanation:
A transposon, also known as 'jumping genes', is a particular sequence of DNA that can relocate inside of the genome. It affects the genetic identity and can be made use of to either reverse a mutation or create one - it duplicates that genetic sequence. Retrotransposons is a class of TE found in viruses.

An example of positive feedback loop would be: A. the release of glucagon in response to low blood sugar B. all of the above C. the release of a hormone in response to a single stimulus D. the release of oxytocin in response to stretching of the uterus
D. The release of oxytocin in response to stretching of the uterus.
Explanation:
There are two types of feedback loops, negative and positive.
Negative feedback loops' main goal is to maintain homeostasis, or equilibrium within the body. When there is a stimulus, the negative feedback loop will try to make the output less than it is, to make homeostasis equal again. An example of this would be regulating blood sugar. If your blood sugar levels are low, your body will release glucagon to make them higher, that is a negative feedback loop.
Positive feedback loops' main goal is to make the reactions go by more quickly, it makes the equilibrium unstable while accelerating the reaction. An example of this would be releasing chemicals in the body such as oxytocin, during childbirth to make it less painful and to speed up the process.
Which phrase describes a feature of an earthquake’s epicenter?
starting point of an earthquake
place around the center of an earthquake
region directly above the focus
point about 100 kilometers deep in the lithosphere
Answer:
It is answer c
Explanation:
i know this because The epicenter is directly above the earthquake's hypocenter (also called the focus)
The phrase which describes a feature of an earthquake’s epicenter is: C. region directly above the focus.
An earthquake can be defined as a sudden, natural shaking of the ground, as a result of movements within the Earth's crust and upper mantle (lithosphere) that typically creates seismic waves.
An epicenter is the point on the surface of planet Earth, which is perpendicular to the hypocenter (focus) and it indicates where the seismic waves from an earthquake are most intense.
On a map, an earthquake’s epicenter is located at the point where the three (3) circles intersect because earthquake are generally shallow.
