Answer:
The correct answer is - A. RY, rY, Ry, ry
Explanation:
Gametes are the sex cells or reproductive cells that are haploid in number. Gametes carry only one allele of each gene or chromosome in any organism. The male gamete called an egg or ovum whereas the male gamete called sperm or pollen.
In this case, the heterozygous plant has the genotype RrYy. In each of the gametes, there would one allele of each gene. The gametes get a dominant R and a dominant Y allele and a recessive r and a recessive y allele. Each produces 25% each of RY, Ry, rY, and ry.
which of the following best describes how the population evolved ?
Answer:
The population has evolved because there was a change in allele frequencies.

Answer:
ball rolling down a hill (remember to convert both time measurements to the same unit).
The graph below shows changes in the populations of two species that interact only with each other over a period of time.
Which statement best describes these two species?
Species A is a producer and species B is its consumer.
Species A is a host and species B is its parasite.
Species A is a predator and species B is its prey.
Species A is a scavenger and species B is its decomposer.
The statement that best describes the two species depicted in the graph is option C) Species A is a predator and species B is its prey.
Option A indicates that species A is a producer and species B is its consumer. This means that species B requires the output from species A to survive. Knowing this, we would expect to show that species B increases in population as the population of A increases, due to increased food supply, the graph shows the opposite scenario. Thus, option A is false.
Option B states that perhaps Species A is a host and species B is its parasite. This provides the same conditions and dependencies as option a, so for the same reasons that a is false, we can conclude that option B is false as well.
The final incorrect option is D, Species A is a scavenger and species B is its decomposer. This would mean that as the population of species B dies off, it increases the food supply of Species A which feeds on the decomposing members of species B. We would expect in this case, that species A would flourish as B dies off, however, we see that as species B dies, species A follows shortly after. This tells us that option D is incorrect.
The correct option is C, Species A is a predator and species B is its prey. This would mean that species A consumes the members of species B to survive. Therefore we would expect to see
Species B thrive as the population of A remains lowFollowed by the steep decline of species B's population as more predators begin to appear. Once the population of species B reaches a critical point, species A will not have enough food supply to sustain its population, and both populations would decline.
This is exactly what the graph depicts, so option C is correct.

Describe the traits that would have existed in early eukaryotes.
Answer:
Early Eukaryotes were single-celled organisms that were present more than 1.6 to 2.1 billion years ago.
Explanation:
-Eukaryotes could be found in a variety of shapes and had a nucleus, a flexible membrane, and a cytoskeleton.
-Early eukaryotes used oxygen in metabolism.
Answer: Many traits found in eukaryotic cells today would have been found in early eukaryotic cells. First, early eukaryotic cells would have had membrane-bound organelles. Also, DNA probably contained introns since this is seen in many eukaryotic cells today. Chromosomes were probably linear in shape. Lastly, these cells would have had mitochondria and membrane-bound organelles. Since these are seen in all eukaryotic cells today, we can infer that they would have been around in early eukaryotes as well.

Pls help me I am stuck I don't know this pls help.
Answer:
DNA starts off on the nucleus where it then gets separated into DRNA so that it can travel to other parts of the cell. It is the. Carried by vehicle to the rough ER where ribosomes are added to it then it goes to the smooth ER where waste is expelled. Finally, it goes to the Golgi apparatus where it is either stored or carried to a part of the cell.

The two distinct layers of the integument consist of a layer of stratified squamous epithelium called the ______ and a deeper layer of areolar and dense irregular connective tissue called the ______.
Answer:
Epidermis and Dermis
Explanation:
The two distinct layers of the integument consist of a layer of stratified squamous epithelium called the Epidermis and a deeper layer of areolar and dense irregular connective tissue called the Dermis.
The Epidermis is the outermost layer of the skin while the Dermis can be found under the epidermis and is also known as the thickest layer thereby providing strength to the skin
What are the benefits for blacktip sharks?
Answer:
Blacktip reef sharks are a critical source to help maintain the delicate balance of marine life in reef environments. They keep fish populations in check and the reefs healthy. However they are highly valued for their meat, fins, leather, liver oil, and fishmeal which makes them prone to overfishing and targeting, and they are endangered yet they are also highly valuable in tourism.

Explanation:
explain why a plant that does not get enough nitrate has weak growth
Answer:
Nitrate deficiency
Explanation:
Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .

when a vegetable gets put in salt water and collapses why does this happen
Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute(like salt) is lower to a region where the concentration of solute is higher through a semipermeable membrane.
Salt water is a hypertonic solution as the concentration of salt ( solute) is higher. Therefore, in this case water from vegetable will move outside causing the cells to become fragile.

can someone tell me what the function is pls i’ll give brainiest
Answer:
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
Explanation:
Lysosome digest worn out cell and destroyed invading viruses and bacteria
Vacuole help to maintain water balance
Mitochondria is produced energy to cell in form of ATP

if an element has a half-life of 30 million years and there is 12.5% of it remaining in a rock, how old is that rock
Answer:
The half-life of a substance is the amount of time it takes for half of that substance to decay. However, after two half-lives, half of the half remaining will decay, leaving you with one quarter of the original substance.
So, after 1 million years you will have 50% of the original substance remaining.
And, after 2 million years you will have 25% of the original substance remaining.
After 3 million years you will have 12.5% of the original substance remaining.
And after 4 million years you will have 6.25% of the original substance remaining.
