Asexually reproducing animal populations are rare, but they typically consist of females who produce female offspring, so all offspring can produce more offspring. By contrast, half of the offspring of the sexual reproducers are male and cannot produce offspring. Thus, a clonal population of females can expand much more quickly than a population of sexual reproducers.
Potamopyrgus antipodarum is a species of freshwater snail that has spread far beyond its native New Zealand. Some populations of these tiny snails reproduce sexually, and other populations reproduce asexually. Huge asexual populations are now disrupting ecosystems all over the world, particularly where the water is contaminated with phosphorus. Fertilizers and detergents contain phosphorus, so agricultural runoff and other forms of water pollution are common in these regions. Like most animals that cannot reproduce sexually, the asexual snails have at least three sets of chromosomes; like most sexual organisms, the sexual snails have two. Explain why sexually reproducing snail populations predominate in regions where the water is unpolluted.
Answer:
Because of the fact that Snails cannot survive in nasty water.

Urea was too big to fit through the pores in regions III, IV, or V.
B
There was no concentration gradient for urea in regions III, IV, or V.
С
There was no urea in the blood in regions III, IV, and V.
D
The pore size was too small in regions III, IV, and V.
Answer:B
Explanation:bc all of the other ones was equal together and the concentration gradient could not spread them
Answer:
The correct answer is
b
Explanation:
First we can elimenate A and D because the pore size is the same.

Which statement is correct regarding the semiconservative nature of DNA? Best answer will be marked brainliest
A. Nitrogenous bases in each “parent” strand serve as a template for the new strand to be made
B. The semiconservative nature of DNA allows DNA to stay the same during gamete (egg and sperm) production
C. RNA operates as a template to allow DNA to replicate itself using ribosomes
D. The structure of the sugars on the DNA molecule direct the correct nucleotides into place during replication
The semiconservative nature of DNA means that Nitrogenous bases in each
“parent” strand serve as a template for the new strand to be made
The semiconservative nature of DNA means that the DNA has two helices
which are created from one strand of the helix. The other DNA acts as a
template in which the new DNA is copied from.
A new DNA double helix consists of a hybrid of one strand of old DNA which
are bound to one strand of newly synthesized DNA to ensure the daughter
cells have unique features.
This feature makes DNA profiling important in identification as individuals
have a unique DNA.

Explanation:
it can be -- AO or AB or BO
plus factor will depend upon enzyme presence.
If a person is having both anti-A and anti-B antibodies in blood then the possible blood group of that individual can be O. However, Rh factor cannot be determined by this information.
What is Blood Group?Blood grouping is the system of classification of blood on the basis of antibodies and antigens in blood which are inherited substances present on the surface of the red blood cells.
Blood groups are classified into four types. These are A, B, AB and O. Blood group A has antigens A on the RBCs with anti-B antibodies present in the plasma. Blood group B has B antigens on RBCs with anti-A antibodies in the plasma. Blood group O has no antigens on the membrane of RBCs and antibodies of both types anti-A and anti-B antibodies in the plasma. Blood group AB has both A and B antigens, but no antibodies in the plasma.

The red squirrel is a species of tree squirrel that can be found in parts of Europe and Asia. In an experiment, a researcher introduced small populations of red squirrels to two different ecosystems at the same time. One of the ecosystems was a large nature reserve. The other was a city park that was about one-fourth the size of the nature reserve. The graph below shows the red squirrel population in both ecosystems over three years.
red squirrel population graph
The graph shows that while the red squirrel population was higher in the nature reserve than the city park, the city park still had a carrying capacity significantly more than one-fourth that of the nature reserve. Which statement could explain why the carrying capacity of the city park was higher than expected?
A.
The nature reserve is much larger than the city park, so its carrying capacity is greater.
B.
The city park contains fewer natural predators of the red squirrel than the nature reserve.
C.
The red squirrels in the city park face intense competition for a limited number of resources.
D.
The red squirrels in the nature reserve are better adapted to live in their environment.
Answer:
B. The city park contains fewer natural predators of the red squirrel than the nature reserve.
Explanation:
When compared to a nature reserve a city park really doesn't have any predators apart from some cats or birds. There really isn't much that can challenge the squirrel in order for their numbers to go down. There is no threat from food shortages and no threat from being eaten by larger animals that could live there.
Answer:
the number of trees in the city park may be limited by humans
the nature reserve may be much larger in area than the city park.
increasing human activity in the city park may disrupt mating opportunities.
Explanation:
The carrying capacity of an ecosystem is usually determined by a combination of factors. Examples of such factors include the boundaries of the ecosystem, the climate, the type and amount of resources available, competition for those resources, and predation.
The researcher's experiment showed that, with respect to the red squirrel, the carrying capacity of the city park is much lower than that of the nature reserve. The possible explanations for this difference are numerous but might include statements like
the nature reserve may be much larger in area than the city park,
the number of trees in the city park may be limited by humans, or
increased human activity in the city park may disrupt mating opportunities.
Any or all of these factors may be responsible for the different carrying capacities of the two ecosystems.
The chemical formula for glucose, a simple sugar, is CH120g. When a glucose molecule is assembled during photosynthesis, the process takes up 12
hydrogen ions from the stroma of the chloroplast. What process adds 12 hydrogen ions to the chloroplast?
A 6 water molecules splitting apart during the light-dependent reactions
B
12 water molecules splitting apart during the light-dependent reactions
C 12 water molecubos splitting apart during the light-independent reactions
D. other sugar molecules reacting with oxygen in the chloroplast
Answer:
A, 6 water molecules splitting apart
Explanation:
I believe the energy from the sunlight is used to split the water. Then we are left with its electrons, hydrogen, and oxygen. Also, photosynthesis only uses 6H2O molecules, so A seems most logical.

Possible answers are :
Condition 1
Condition 2
Condition 3
Condition 4
Answer:
condition 3
Explanation:
Water moves from a high concentration to a low concentration across a permeable membrane by osmosis.
For a net loss of water to occur in the cell, water has to move outside the cell.
Therefore, the concentration of water inside the cell has to be higher than the concentration outside the cell.
This is true for condition 3, where the concentration inside is 95% and inside is 90%

Assume a snake must eat 5 grasshoppers per day, while an eagle must eat 2 snakes per day. how many blades of grass are needed to keep an eagle alive for a day?
Answer:
100 blades
Explanation: (=10 blades/grasshopper x 5 grasshoppers/snake x 2 snakes/eagle)
The number of grass blades required to keep an Eagle alive can be calculated using the multiplication of 10, 5 and 2 is 100 blades.
Number of snakes an Eagle must eat = 2 per day
Number of grasshoppers a snake requires per day = 5 per day
To keep an Eagle alive ;
10 blades of grass are required to keep grasshopper alive 5 grasshoppers are required to keep snake alive2 snakes are required to keep Eagle alive ;Therefore, the required number of grass blades needed will be :
10 × 5 × 2 = 100 bladesHence, the number of grass blades required to keep an Eagle alive is 100.
