Understanding the Pericardium (Pericardial Sac) Your heart is surrounded by a double-layered membrane, called the pericardium or pericardial sac. This membrane keeps your heart in place in your chest cavity, restricts the expansion of your heart when your blood volume increases, and helps to protect your heart

Answer:

The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.

Answer:

C. Double helix

Explanation:

The twisted ladder shape that DNA has can also be called a double helix.

It is in the shape of a helix, which is similar to a 3D spiral shape.

It is called a double helix because DNA is made up of two DNA helix strands that are intertwined.

So, C is the correct answer.

Answer:

The answer is C. double helix.

Explanation:

DNA is constructed through two threads or strands winded around each other in the shape of a twisted ladder - hence one of the shape of a DNA's most prominent nicknames (that is, twisted ladder). Additionally, it is even more commonly known as a double helix. In fact, the term double helix was especially created to describe DNA!

Answer:

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

Explanation:

This is what the cell membrane does so if any of these are an answer choice then use process of elimination to figure out which one is correct

its does not provide energy

Explanation:

Answer:

The carrying power of a small, mountain stream in the mountains with that of a slow large river that is about to enter the sea is explained below in details.

Explanation:

A mountain stream is a river or stream, normally with a sheer slope, running down a mountainside. Stream velocity is most noted in midstream near the exterior and is crawling along the stream bottom and shores due to friction.

The river stalls down at the entrance, so it doesn't have the energy to carry all the sand, dirt, and clay anymore. These deposits create the flat, regularly triangle-shaped tract of a delta.

Answer:

i would say B

Explanation:

Fossils can tell us about the size depending on how large the bones are. The year of death could possibly be determined by the way the bones look maybe, same with the environment, showing what type of animal; it could be a type of fish. But I believe there is no way fossils could show the diet and behavior of the animal.

Meiosis is the cell division that enables sexual reproduction. It consists of two successive cell divisions, after which four genetically different cells are obtained, which contain half the number of chromosomes as the mother.

Answer:

Each bite passes through several "cells" within the digestive system, and each of them has a specific function in terms of processing uneaten food.

Explanation:

The food begins to be processed in the mouth and prepared for the upcoming digestion process.

Saliva is important for food processing, among other things because it contains the enzyme ptyalin (alpha-amylase), which is responsible for the breakdown of starch and glycogen and continues its activities in the stomach.

Well-chewed food passes through the pharynx to the esophagus. During the swallowing of food, the opening of the trachea is closed, although it is possible that some crumb of food strays and causes a strong cough, which expels the excess from the trachea.

From the esophagus, food comes into the stomach, which is surrounded by ribs. Stomach acid is extremely strong and enables the conversion of food into liquid, which facilitates the further process of digestion.

Food from the stomach continues its way through the digestive tract to the duodenum, from the duodenum it reaches the small intestine.

Food processing in the large intestine is the last phase of digestion of food in the digestive tract. When the waste materials reach it, they need up to 24 hours to pass through the large intestine and reach the other end.

Incomplete question. The options;

a) yes, gm fish could alter biodiversity if they mate with fish in the wild. This impact is best minimized by producing gm fish that are sterile.

b) yes, gm fish can alter biodiversity if they mate with fish in the wild. This impact is best minimized by tracking the released fish and capturing them.

c) no, gm fish cannot impact natural ecosystems because they are likely to die in the wild. There is no need to be concerned about the impact to nature.

d) no, gm fish cannot impact natural ecosystems because they are designed.

e) there is no need to be concerned about the impact to nature.

Answer:

a) yes, gm fish could alter biodiversity if they mate with fish in the wild. This impact is best minimized by producing gm fish that are sterile.

Explanation:

Indeed, genetically modified (GM) fish basically refers to fish whose natural traits have been edited or adjusted by scientists. For example, they may be modified in such a way that they feed more and grow faster than is usual for wild fish. Biodiversity is altered when these GM fish begin to consume more food and also producing offsprings with similar traits, over time this would make it difficult for natural wild fishes to find food; reducing their population, thereby impacting nature.

However, if GM fish are produced to be sterile (ie cannot reproduce offsprings), it could easily lead to a balance in the population of the natural ecosystem.

2. Liquid

3. Gas

Answer:

A cross between a roan bull (Ww) and a white cow (ww) produces roan and white phenotypes in a 1:1 ratio.

Explanation:

Two alleles are influencing the color of the hair of the cow-W red and w white.

These alleles show that a hybrid Ww has red hair. The genotype of the bull is Ww, WW is red and ww is white. So, mixing the red and white cows is 1:1.

Answer: Active transport requires energy to move substances across a plasma membrane, often because the substances are moving from an area of lower concentration to an area of higher concentration or because of their large size.

Answer:

Spindle fibers because they split the cell

Explanation:

Answer:

The correct answer is -

Parent 1: RW, Parent 2: RR

Explanation:

In the given punnet square there are four offspring and it is a monohybrid cross between parent 1 and parent 2. The four offspring produced in this cross have RR, RR, RW, and RW alleles. By the genotype of the offsprings, it is clear that there are 50 percent pure or true-bred and 50 percent are heterozygous.

Each parent contribute two alleles and these alleles are independently assort in the zygote to form offspring so there must be R, R, R and W allele present in the parent

Parent 2  →       R     R

Parent 1 ↓     R  RR   RR  (one allele (R) come from each parent in zygote)

                    W  RW  RW (one allele  (R and W) come from each parent)

Answer:

There are 60 grams of the salt in 12 teaspoon of it

Explanation:

We can rephrase the question by saying, if 1 teaspoon has 5.00 grams of salt, how many grams does 12 teaspoon have? We can then equate the answer by doing the following

1 teaspoon = 5 grams

12 teaspoon = ?

Cross-multiply

? = 12 × 5/1

? = 60 grams

There are 60 grams of the salt in 12 teaspoon of it
