Answer:
c
Explanation:
there will be way less vegetation to attract pet and many organisms will die because of the lack of resources due to the drought
If the desert experiences a prolonged drought where many of the plants die, the carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.
What is ecosystem?"An ecosystem consists of all the organisms and the physical environment with which they interact."What do you man by carrying capacity?"The carrying capacity is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available."Due to draught, resources decreases (resources becomes limited) and many organisms would die because of starvation. This would also effect in the food chain of other organisms. The organism would now compete for the lesser amount of resource.
Hence, the correct option is C. The carrying capacity of the ecosystem will decrease because there will be less food available for many organisms.

OB. A soccer ball is at rest on the feld.
OC. Afireman turns on his hose and he is knocked backwards.
O
D. The water is falling down the cliff to form a waterfall.
Answer:
The best demostration that applies to Newton's Third Law of motion would be D) When you walk your foot pushes down on the ground while the ground pushes back on your foot.
Explanation:Newton's Third Law states that for every action, there is an equal and opposite reaction. This is actually explains that forces come in pairs and forces are an interaction between two objects. As per the correct option given in the question explains Newton’s Third Law.
When you walk your foot (say object A) pushes down on the ground while the ground (say object Q) pushes back on your foot with the same force but in the opposite direction.
E. coli strain B is doubly infected with two rII mutants of phage T4. 0.2 ml of a 108 dilution of the progeny is plated on E. coli B and 0.1 ml of a 104 dilution of the progeny is plated on E. coli K. 16 plaques appeared on strain B, 400 on strain K. Calculate the recombination frequency between these two mutations.
To Find :
The recombination frequency between these two mutations.
Solution :
Formula of calculating recombination frequency is :
[tex]R.F = \text{Number of mutations}\times \dfrac{\text{number of k plaques} \times D.F }{\text{Volume used}}\times \dfrac{Volume'}{\text{Number of B plaques} \times D.F' }}[/tex]
Putting all given values in above equation, we get :
[tex]R.F = \dfrac{2\times 400\times 0.2 \times 10^4}{16\times 0.1\times 10^8}\\\\R.F = 0.01[/tex]
Therefore, the recombination frequency between these two mutations is 0.01 or 1 %.
Given:
No. of mutation = 2Volume, [tex]V = 0.1[/tex][tex]V'= 0.2[/tex]
k plaques = 400The formula:
→ [tex]R.F = No. \ of \ mutations\times \frac{No. \ of \ k \ plaques\times D.F }{Volume}\times \frac{Volume'}{No. \ of \ B \ plaques\times D.F'}[/tex]
By putting the values in the above formula, we get
→ [tex]= \frac{2\times 400\times 0.2\times 10^4}{16\times 0.1\times 10^8}[/tex]
→ [tex]= \frac{160\times 10^4}{1.6\times 10^8}[/tex]
→ [tex]= 0.01[/tex]

If an organism has a diploid number of 50, and one of its cells undergoes meiosis, what is
the number of daughter cells and how many chromosomes will each one have?
Answer:
for me
Explanation:
it's 25
because di is 2 and ha is 1
If an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.
What is Diploid?Diploid may be defined as a condition that determines the existence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair.
On contrary, haploid cells generally contain only a single set of chromosomes. These types of cells are formed due to the process of meiosis, while diploid cells are formed by the activity of mitosis.
According to the question, if a diploid number of an organism = 50.
This means that 2n = 50,
n = 25.
As we all know that when a cell undergoes meiosis, it will definitely have half the amount of genetic content in its daughter cells.
Therefore, if an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.

The platypus bill has a multitude of receptors on it. Initially, researchers thought that the receptors were all mechanoreceptors (i.e. for sensing textures, shapes) because platypus can not smell or detect odors underwater. The scientific community was shocked (pun intended) when it was reported that some of the receptors were actually electroreceptors. Design an experiment to determine if platypus prefer to hunt for prey through mechanoreception or electroreception
Answer:
Experiment: to put insect preys with different textures (but of the same group, for example, moths) into two conditions: 1-pure water and 2-ion-rich water solution. For this experiment, it is important to highlight that the platypus is a semiaquatic mammal that eats insects that fall into the water. Pure water is a poor conductor of electricity, while water containing charged ions (and also impurities) is a good conductor of electricity. In consequence, if the platypus prefers to hunt through electroreception, it is expected that the ability for hunting will be better in an ion-rich water solution than in pure water. Second, if the platypus prefers to hunt through mechanoreception, it is expected that the ability for hunting will vary depending on the type of texture that exhibits insect preys (in this case, moths).
Explanation:
Mechanoreception can be defined as the ability to detect and respond to a stimulus by using sensory cells (neurons) that respond to mechanical pressure and/or distortion, while electroreception is the ability to respond to electrical stimuli, thereby detecting weak electric fields in water. In the experiment above described it is possible to determine the hunting preferences under differential electroreception/mechanoreception conditions. Statistical scores such as p-value can be used to determine the outcome of the experiment.

Answer:
1- Test tube with DNA sample is placed in machine
2- DNA sample is heated
3- DNA denatures
4- Taq polymerase initiates DNA synthesis
5- Double-stranded DNA is produced
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to produce many copies of a specific DNA sample. Thermocyclers are machines designed for a cyclic temperature change of the PCR. First, an initial denaturation step where DNA sample is heated to separate the double-stranded DNA into two single strands. Subsequently, 20-40 PCR cycles are repeated to produce millions of copies of a specific DNA sequence. There are three steps in each PCR cycle: 1-Denaturation to 94–98 °C (DNA strands are separated), 2-Annealing to 50–67 °C (primers bind to each DNA strand on the opposite ends of the DNA strands to be copied) and 3-Extension to 75–80 °C (Taq polymerase initiates the synthesis of complementary DNA strands).

When Lake Mendota was completely covered with algae, biologists used the concept of trophic cascades to solve the problem by introducing predatory fish. When they did this, a\an ________ in predatory fish caused a\an ________ in plankton feeding fish, which resulted in a\an ________ in\ herbivorous plankton with a consequent ________ in algae. Group of answer choices increase; increase; increase; decrease increase; increase; decrease; increase decrease; increase; increase; decrease increase; increase; decrease; increase increase; decrease; increase; decrease
Answer:
increase; decrease; increase; decrease
Explanation:
When Lake Mendota was completely covered with algae, biologists used the concept of trophic cascades to solve the problem by introducing predatory fish. When they did this, an increase in predatory fish caused a decrease in plankton feeding fish, which resulted in an increase in herbivorous plankton with a consequent decrease in algae.
With the introduction of predatory fish, a decrease in the population of zooplankton-eating fish would occur due to predation by the newly introduced fishes. This will cause the population of zooplankton to thrive or increase.
Zooplanktons feed on algae. Hence, an increase in their population will put pressure on the alga in the ecosystem and cause a decrease in their population.

Which enzyme would most likely function in the stomach?One or more polypeptide chains of amino acids make up a big protein enzyme molecule. The unique protein folding patterns, which are crucial for enzyme specificity, are determined by the amino acid sequence.
Pepsin and rennin are the two primary enzymes found in gastric juice. While rennin coagulates the soluble milk protein, casein, into an insoluble curd, which is then attacked by pepsin, pepsin breaks down proteins into short polypeptide chains. Pepsin is produced by the chief cells of the stomach as pepsinogen, an inactive zymogen.

Why is the cell like a city?
Answer:
The cell is basically like a city because there are different parts of the cell that work together to keep a system running, therefore incredibly similar to a cell. There are parts to the cell such as the vacuole which acts as the storage for a cell, like the storeroom or bank in the city, and the lysosome which cleans up and recycles for the cell in away, acting as the recycle center or such for a city. Just like these few cell parts, there are many other parts which each have their respective "role" to functioning as a "city", and for those reasons a cell is like a city.
