Answer:
There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.
I hope this helped
The combinations in the alleles that are carrying out the genotype of AaBb then at that stage the alleles combinations that will be present in their gametes will be AB, ab, Ab and aB.
What is a genotype ?It is defined as the genetic expression of an individual. It defines the traits and the characters that are present in the individual in order to decide the phenotype of an individual.
In the genotype of AaBb, it is the combination as the both of the genes copies are present and in this case due to very obvious reasons it is the capital one that is going to express itself. The other genes are definitely present but with a effect that will be covered out by the dominant one.
The 4 combinations that will be present are AB, ab, Ab and aB where the 1st one where the both of the dominant ones will be present will be carrying the dominant genes, ab in this the recessive ones will be present and in others ones, one dominant and one recessive is present.

What types of cells have cell walls ?
The type of cell that possess cell wall is plant cell. The correct option is A.
What is cell wall?A cell wall is a structural layer located just exterior the cell membrane that surrounds certain types of cells.
It can be tough, flexible, along with being rigid at times. It basically aids structural support as well as protection to the cell, as well as acting as a filtering mechanism.
The cell wall is made up of a network of cellulose microfibrils and cross-linking glycans embedded in a matrix of pectin polysaccharides that is highly cross-linked. Lignin can be found in secondary cell walls.
Plant cell walls, as the interface between adjacent cells, frequently play important roles in intercellular communication.
Plant cell walls play an important role in plant-microbe interactions, including defense responses against potential pathogens, due to their surface location.
Thus, the correct option is A.

Please help worth 95 points. Project: Algae Cultures: Directions
In this report, you will be researching the different types of algae. Report on one algae from each of the three categories (blue-green, green, and green-brown). Include the following information: Name of the algae, Category if falls under, Where it is mostly found and what conditions it needs to survive, Whether it is unicellular or multicellular, Where in the food chain algae are, and what predators it may have, Research why some scientists think algae should be classified plants, and explain the debate.
1.Which organisms did you identify 2. How easy or difficult was it to find an example of each category? Which one was the hardest to find? Why? 3. Which environments were most common to find algae in? Why do you think so? 4. What part of the food chain is the alga? 5. Why is algae classified in the Protist Kingdom and not the Plant Kingdom even though they are photosynthetic? Research why scientists feel they should be classified as plants.
Answer:
1) I identified the Golden-Brown Algae.
2) It was very easy to find the category because of the solid color base and because it only had the daitoms. It did not have multiple like the Green Algae and the Blue-Green Algae.
3) In fresh, brackish or salt water. They are found both in tropical lakes and seas, and in the alpine and polar snows. They are unicellular or multicellular protist plant organisms, whose cells do not form tissues and lack flowers. They are considered the first link in the food chain in the aquatic environment. They are found in fresh, brackish or salt water. They are primary producers in the food chain, capable of producing organic substances through photosynthesis, so they use sunlight. They are found in tropical lakes and seas up to the alpine and polar snows.
4) Producer Alga is A plant and produces food for other organisms.
5) Algae (Euglena) do photosynthesis as plants do. They also move around and eat, as do animals. But they are unicellular. In order to be classified as a plant or animal, an organism has to be multicellular, made of more than one cell. Since it is a unicellular organism with some plant and animal characteristics, it is called a protist. Plant cells have walls while algae does't have one, so it is a protozoan. Algae resemble the protozoa, so they are put into the Protist Kingdom.
Explanation:
I had the project.
Algae recreate a major part of the marine ecosystem because they exist as the decomposers current in the marine ecosystem; any harm to them could cause an inequality in the whole marine ecosystem.
What are golden-brown algae?1)The Chrysophyceae, usually named chrysophytes, cryptomonads, golden-brown algae or golden algae exist as an extensive set of algae, seen mainly in freshwater.
2) It stood very easy to see the class because of the solid color base and because it only contained the diatoms. It did not contain multiple like the Green Algae and the Blue-Green Algae.
3) In fresh, saline, or salt water. They exist seen both in tropical lakes and seas and in the alpine and polar snows. They exist as unicellular or multicellular protist plant organisms, whose cells do not constitute tissues and absent flowers. They exist thought the first link in the food chain in the aquatic environment. They exist seen in fresh, brackish, or salt water. They exist as primary producers in the food chain, qualified of producing organic substances through photosynthesis, so they utilize sunlight.
4) Producer Alga exists in a plant and makes food for different organisms.
5) Algae (Euglena) accomplish photosynthesis as plants do. They even move about and eat, as do animals. But they exist unicellular. To be categorized as a plant or animal, an organism contains to be multicellular, made of better than one cell. Since it stands as a unicellular organism with some plant and animal elements, it exists named a protist. Plant cells contain walls while algae don't contain one, so it exists as a protozoan. Algae reach the protozoa, so they stand to put into the Protist Kingdom.

In the African savanna, more wildebeests are born than the environment can support. Which is most likely to happen over a period of years as a result?
The chances for survival of the population are reduced.
New food sources are discovered and become the regular diet.
Individuals that are well suited to the environment reproduce, and those that are not well suited die before they reproduce.
The environment adapts by providing more resources to the growing population, increasing the chances of survival for individuals within the habitat.
Answer: I think the correct answer from the choices listed above is option C. Over a period of years, most likely, individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce. Hope this answers the question.

If a sample originally had 120 Adams of carbon 14 how many atoms will remain after 17,190 years
Answer:
15 atoms
Explanation:
About 15 atoms out of the 120 Adams would remain.
Generally, the half-life of a substance is the time it takes for one-half of that substance to disintegrate.
Carbon 14 has a half-life of approximately 5,730 years. 17,190 years means that the sample had stayed for 17,190/5,730 which is equal to 3 carbon-14 half-lives.
Out of 120 Adams,
the first half-life will reduce 120 to 60 Adamsthe second half-life will reduce 60 Adams to 30 Adamsthe third half-life will reduce 30 Adams to 15 Adams.Hence, at the end of the 17,190 years, approximately 15 Adams would remain.

What type of energy has to do with a change in temperature?
Answer: changes in heat energy change temperature
Explanation: heat energy can be thought of as energy in individual atoms or molecules, which vibrate more as energy increases. Temperature is a measure of heat energy. For example, many substances expand as heat energy causes it atoms/molecules to vibrate more and occupy more space. We can use this property to measure energy as temperature by using the expansion of a liquid as in thermonmeters.
In the experiment, which of the following variables should remain consistent?
the types of plants used
the temperature of the water and vinegar
the type of soil used
All of these choices are correct.
