Answer:
The torso, which houses the apparatus consists of upper and lower cavities that are partitioned by the diaphragm.The upper cavity is called the thorax (or colloquially the chest) and is almost totally filled with the heart and lungs; the lower the cavity, the abdomen or belly, contains much of the digestive system and other organs and glands.
Explanation:
The torso is an important part of the body that contains many of our organs, and its integrity is fundamental to our survival.
The torso is divided into two big cavities (thorax and abdomen) by the diaphragm, the most important muscle involved in breathing. The diaphragm has three large openings that allow the passing of the esophagus, and some blood vessels and nerves from the thorax to the abdomen, and vice versa.
Inside the thorax there's the lungs and the heart, which are separated into specific cavities: the pleural cavity, formed by the two layers of a membrane that envelops the lungs called pleura; and the pericardial cavity, formed by the two layers of the pericardium, which surrounds the heart and the large vessels.
The abdomen holds most of the digestive system, like the stomach, the liver, and the intestines, and has other important organs as well such as the kidneys. The organs from the digestive system are held in place by another membrane called the peritoneum.
In rats, gene B produces black coat color if the genotype is B–, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D–, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. Determine the genotypes of parents of litters with the following phenotype distributions. Part A 4 brown, 4 black, 4 yellow, 4 cream
Answer:
Bbdd and bbDd
Explanation:
From the illustration:
B_dd - black color
bbD_ - yellow color
B_D_ - brown color
bbdd - cream color
In order to produce litters in the ratio 4 brown, 4 black, 4 yellow, and 4 cream; the genotypes of the parents must be Bbdd and bbDd. The cross between the two parents would be such that:
Bbdd x bbDd
4 BbDd - brown color
4 bbDd - yellow color
4 Bbdd - black color
4 bbdd - cream color
See the attached image for the Punnet's square analysis of the cross.

"Histology Lab Tissues are groups of cells with similar shape and function. The purpose of this lab is to give you experience looking at and identifying tissue slides taken from areas all over the body. Epithelium 1. What is the primary purpose of all epithelial tissue? 2. Besides skin, give two examples of different body "surfaces" that are exposed to the outside environment and would need a lining of epithelium. 3. Label the following as squamous, cuboidal, or columnar."
Answer:
1. The primary purpose of all epithelial tissue is to cover the different body surfaces, this includes cavities that are not in contact with the exterior and parts of the body that are in contact with the exterior.
2. Tongue and esophagus.
3. The images with the types of epithelium are attached.
Explanation:
The main purpose of epithelial tissue is to cover all the surfaces of our body. These are the cavities, and the parts that are in contact with the exterior. They create barriers that protect the body, secrete, absorb substances, allow the passage of specific elements, and stop the entrance of others. The functions vary according to where the tissue is in the body.
The tongue, as it is in contact with the exterior and with the food that enters our mouth, it has a stratified squamous epithelium. The thickness of this epithelium protects it against the different things that can damage or enter through it.
The esophagus has a nonkeratinized stratified squamous epithelium that protects the esophagus from the damage, that food or antigens may cause.
Squamous epitheliums have cells with a not specific shape that has their nucleus in the center.
Cuboidal epithelial have lined cells with a cuboidal shape.
Columnar epithelial have lined cells with a rectangular shape, and their nucleus is near the basal region.

1. What did Linnaeus use to classify living things?
Answer:
Perhaps the single greatest contribution Linnaeus made to science was his method of naming species. This method, called binomial nomenclature, gives each species a unique, two-word Latin name consisting of the genus name and the species name. An example is Homo sapiens, the two-word Latin name for humans.
Explanation:
Can I have brainliest
It is from Google
Binomial nomenclature, which Carolus Linnaeus created, is a system for categorizing living things. Linnaeus was a Swedish botanist and biologist.
Binomial nomenclature is a biological system for naming organisms.
It is quite difficult to identify an organism internationally and keep track of the number of species when it has multiple local names.
Some of the features of binomial nomenclature that Linnaeus used to classify living things are:
Latin names are used because they are universal and consistent.
The process of naming each organism uniquely using the two words "genus" and "species."
The arranging of living things into a hierarchy, with each organism being given a position based on how similar it is to others.
Humans, for instance, are known as Homo sapiens. Its name, Homo, translates to "man" in Latin. The name of the species, sapiens, means "wise".
Therefore, Binomial nomenclature is used by Linnaeus to classify living beings.

If you inoculated a lactose phenol red broth with a bacterium and after 24 hours, the broth turns yellow. You accidentally leave it in the incubator an additional 48 hours, after which the same broth turns into a dark red/pink (magenta). This process is called
Answer: Deamination
Explanation: Deamination is simply the removal of an amino group from a compound, in this instance, from peptone in the phenol red broth.
Within 24-48 hours is the time frame which bacteria can be able to fully ferment carbohydrates (glucose or lactose) and after 48 hours, carbohydrate runs out because it has all been utilized leading to a rise in pH (alkaline) as the bacteria utilize peptones to give alkaline by-products.

Cuts heal when growth factors in the dermal layer of the skin signal cells in the epidermal layer to divide. This process takes time and coordination as shown in the figure below. In the past 10-20 years, researchers have conducted many in-vitro and animal studies that have showed promise using growth factors to facilitate healing in impaired wounds, bone regeneration, and nerve regeneration. Researchers hope that the application of growth factors may be used clinically to enhance the wound healing process. The cellular process that enables the cells to grow and develop into tissue is —

The energy used in photosynthesis come from what??
Answer:
chloroplasts.
Explanation:
Chloroplast
Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, much amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in unicellular algae, up to 100 in plants like Arabidopsis and wheat.
