Single-nucleus, striated, branching cells
Multinucleated, non-striated, branching cells
Multinucleated, striated, long threadlike cells

Answers

Answer 1

Answer: Multinucleated, striated, long threadlike cells

A group of similar cells that perform a particular function is called a tissue.

There are different kinds of tissues in both plants and animals. In man, there are four major types of tissue.

1. Muscle tissue - made up of cell that are long and fibrous. The muscle cells are able to contract.

Answer 2

Answer:

Answer: Single-nucleus, striated, branching cells

Explanation: Cardiac muscle cells are striated and branched with a single nucleus. They are joined end to end in complex networks.

What would happen to and its offspring if the cells did not go through a G1 phase during their cell cycle

Answers

G1 is the most important phase of meiosis or mitosis.It is the phase when the first cell growth happens.If G1 never happens,the cell aren't mature and DNA chromosomes won't be condensed.The next phase,S phase,take the DNA and copies them.If the DNA never got condensed and mature in G1 phase,S phase wouldn't be accurately completed and then this could result in mutations,and etc.
Hope this helps:)

Why do phospholipids form a bilayer in water?

Each phospholipid has a hydrophobic (dislikes water) tail, and a hydrophilic (likes water) head. So when added to water, the phospholipids from a ring.

The first animals to live successfully on land were

Answers

it was the reptiles that lived and successfully on land

When you consider evolution, then you have to take into account where all life came from...the Ocean. Specifically micro-organisms in the ocean, they've existed for tens of Billions of years but land organisms around 5 billion years and that's to do with retreating tides etc. So from bacteria a single cell organism you make your way to minor complex organisms with the basic of physiological furniture and that's the 'digestive tract' and these guys are basically worms. Then quite a few million stages after that are the insects, as they improve upon just having only an advanced digestive tract to include other higher ordered functions as well adaptive mechanisms such as flight. But life is more diverse than just one track so it branched off before land dwelling and more than likely we as a species were developed in the ocean as multi-functioning organ-ed fish then onto land as res-pirating fish (such as lung fish, the first example of amphibians) then to higher order amphibians such as salamander types. Of course much of the stages proposed by Darwinian evolution are speculative so you decide :D ik this answer is long but its kinda hard to explain in one short sentence XD

PLZ HELP! 20 POINTS! WILL GIVE BRAINLIEST!1. In the fast change, how are other parts of the ecosystem affected?

2. In decomposition, how are other parts of the ecosystem affected?

3. Under which type of change would more organisms be able to survive? Why?

4. What are some positive effects of a rapid change to an ecosystem?

5. What are some positive effects of a slow change to an ecosystem?

Answers

A change in an ecosystem necessarily affects the species which are part of it, and changes in species in turn affect ecosystem processes. ... This is caused by the extinction of species or loss of populations that had been unique to particular regions and by the invasion or introduction of species into new areas.

Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.

When a food handler can effectively remove soil from equipment using normal methods, the equipment is considered what?

Answers

When a food handler can effectively remove soil from an equipment by using normal methods, the equipment is considered to be; Corrosion Resistant.

The soil referred to her would be dirt because we are talking about a food handler.

Now, if the food handler is finding it difficult to remove dirt from the equipment by using normal/regular methods, it means that the soil/dirt has succeeded in having some kind of chemical reaction with that equipment.

If that is the case, then it means the equipment is undergoing corrosion because corrosion is defined as the gradual destruction of a metal by chemical reaction with the environment.

Since we have established that inability to use normal method denotes corrosion, then if he can use normal methods to remove the soil effectively, then the equipment is said to be corrosion resistant.

Final answer:

When soil can be effectively removed from equipment by a food handler, the equipment is deemed sanitized. Sanitization involves cleansing to remove microbes to levels that are safe for public health. It's applicable to fomites, objects that can harbor microbes and facilitate disease transmission.

Explanation:

When a food handler can effectively remove soil from equipment using normal methods, the equipment is considered sanitized. Sanitization refers to the cleansing process used to remove enough microbes to achieve levels deemed safe for public health. This is especially crucial in the food service industry, where items like dishes are cleaned with hot water and air, killing most microbes. It's also applied to inanimate items, known as fomites, which can harbor microbes and aid in disease transmission like door knobs or toys. The level of cleanliness required for a fomite depends on the application for which the item will be used and the level of resistance to antimicrobial treatment by potential pathogens.
