What are the possible genotypes for fur in each of the two guinea pigs shown here?
Answers
Answer:
black guinea pig:
1. BB
2. Bb
white guinea pig
1. bb
Explanation:
The black guinea pig carries the dominant trait. The "B" represents dominant trait. the "b" is recessive. When a dominant trait (B) is present, it will always take over making the guinea pig have black fur regardless of if there's a recessive trait. In order to get the white fur, you will need two recessive traits (bb).
The genotypes of 2 guinea pigs, for 2 traits are represented as AABB and aabb. The guinea pigs are mated and the offspring eventually mate with each other.
What is the meaning of genotypes?
A genotype is a genetic arrangement that makes up the traits that an organism inherited from its parents. Genotype can also mean the entire collection of genes an offspring inherited from its parents. In animals, a material known as DNA acts as the instructions that tell cells what to do.
What's a genotype ratio?
The genotypic ratio is the ratio depicting the different genotypes of the offspring from a test cross. It represents the pattern of offspring distribution according to genotype, which is the genetic constitution determining the phenotype of an organism.

Mendel's principles of heredity apply to many organisms, including animals. For example, in guinea pigs, black fur (B) is dominant over white fur (b). What are the possible genotypes for fur in each of the two guinea pigs shown here?
Answers
In guinea pigs, the gene for black fur, B, is dominant over the gene for r white fur, b recessive, so the possible genotypes for fur in each of the two guinea pigs are BB X bb = Bb, Bb, Bb, Bb.
What are genotypes?
Genotype is the genetic appearance of the organism which shows all the traits in the genetic appearance but in the physical aspect, it only shows the dominant trait.
The cross between BB X bb
Gametes: B and b
Genotype = Bb, Bb, Bb, Bb.
Phenotype: all offspring are having black fur.
The cross is attached in the image below.
From the analogy shown, it is obvious that one parent has a gene with black fur and the other has white fur. During such crossing, the offspring are two homozygous dominant black fur and two homozygous recessive black fur.
Therefore, genotypes for fur in each of the two guinea pigs are BB X bb = Bb, Bb, Bb, Bb.

if the density of water is 1 g/ml, what is the mass of 3ml of water?
PLEASE HELP
Answers
You can use dimensional analysis to figure this out.
[tex]=3\ ml[/tex] × [tex]\frac{1g}{ml}[/tex]
= 3 grams
If done correctly, ml and ml will cancel out, leaving you with grams.
If you don't know dimensional analysis, simply multiply 3 ml by 1 grams and that should still get you 3 grams.

2. What process can cause rock to move up to Earth's surface?
Answers
Answer:
1.) "Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment (and soil) from the place of weathering. Liquid water is the main agent of erosion. Gravity and mass wasting processes move rocks and sediment to new locations."
2.) "Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away."

Answers
Answer:
1.Plant cells have a cell wall, but animals cells do not.
2.Plant cells have chloroplasts, but animal cells do not.
3.Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
Explanation:
Hope this helps, sorry if I'm wrong
Brainliest would be nice. :)
Answer:
In the plant cells, it is noticeable that there's a cell wall, which basically consists of cellulose, and is responsible for guaranteeing resistance and form to the cell, also protecting it from pathogens, a Characteristic that isn't found on animals cells.
The format of the cells is also different due to the animal cells being round and having an irregular form, while plant cells have fixed and rectangular forms.
The plastids are organelles that are exclusive to the plant cells and are characterized by the presence of double-membrane and DNA. They possess the function of storing and photosynthesis.
Note: The difference between these cells is a lot, and is mainly based on the presence and absence of organelles.

Answer:
I would say D is correct.
Explanation:
Animals can't create what we now consider 'music' and 'art', or read/write. While animals do speak in some type of language, it's different for every species. And for sure, Animals haven't made advanced technologies. So that would make all of those things go onto the 'human side', making it D instead of any of the other options.

What is a wildlife park?A wild life park is an area where animals are allowed to roam around freely as if they are in the wild. The animals are not caged because the system aims to imitate the natural habitat of the animals.
This approach can help conserve endangered species and at the same time retain the same features of keeping the animals in the wild which is a huge plus for this system.
However, the issues with poaching can ruin the usefulness of this approach in the future. This limitation can be addressed by providing adequate security in the wildlife park as well as further dependence on technology to prevent poaching.

1. How do rock formations move between Earth’s surface and interior?
2.What happened to the igneous and sedimentary rock formations during plate motion?
Answers
Answer:
1) Plate motion moves rock formations. Subduction moves rock down, below Earth’s outer layer.
2)At diverging plate boundaries, convection currents bring hot magma to the surface. This hot magma flows out onto the ocean floor, forming extrusive, finely grained igneous rocks. At convergent plate boundaries, sedimentary rock from the ocean floor gets pushed down into the mantle.
Explanation: none :)
Answer:
How do rock formations move between Earth's surface and interior?
Plate motion moves rock formations. Subduction moves rock down, below Earth's outer layer. Uplift moves rock upward, toward Earth's surface
What happened to the igneous and sedimentary rock formations during plate motion?
The igneous rocks are eroded and turned into sedimentary rocks. The sedimentary rocks layers generally tend to be recycled by plate tectonics. The deep ocean sediments are turned back into igneous rocks where they are pushed back into the mantle at subduction zones.
