Answers

Answer:

Hey mate......

Explanation:

This is ur answer.....

1. Ruminant stomachs have four compartments, and monogastric stomachs have only one compartment. Ruminants are able to digest grasses and other fibrous feeds better than animals with monogastric systems can.

2. The bacteria can digest fiber allowing the dairy cow to consume grass, forages, and fibrous by-product feeds that humans or monogastric animals cannot do effectively. The abomasum is the stomach compartment similar to the human stomach.

Human Body: the physical substance of the human organism, composed of living cells and extracellular materials and organized into tissues, organs, and systems.

What is the ultimate source of energy for all living things? A. Food B. The sun C. Water D. Oxygen​

Answers

Answer:

B, The sun.

Explanation:

The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

What makes human beings different from other animals?​

Answers

Human beings have brains that distance them from animals they also spend the most time with their parents unlike many animals and human beings also have a very high level of intellect which isn’t found in animals

Answer:

   There are many characteristics in humans that can define us to be different than other animals. For example, our body. Humans are generally more flexible than animals. One can bend in different ways while other animals are minimalistic in comparison to our flexibility. Another example is our life span. Humans have more life span than most animals but not all. Many animals have lesser life span from days, months to few years with exception of tortoise, elephants which have more than ourselves. Like I said in the beginning, there are many more traits that differ us from other animals.

g Knowing if a bacterium is Gram-positive or Gram-negative is important in medicine because it tells us what type of antibiotic will be used (e.g., penicillin for Gram-positive bacteria and mycins, like streptomycin, for Gram-negative bacteria). Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a True b False

Answers

Answer:

This is true.

Explanation:

Knowing whether a bacteria is gram positive or negative will help to narrow down the types of pathogen it could be and will determine which antibiotics will be effective against it.

Knowing whether a bacteria is gram positive or gram negative will help to understand the kind of infection it may cause and thus help in determining the kind of antibiotic it needs.

What are gram-positive and gram-negative bacteria?

The bacteria that have a thick layer of peptidoglycan but no outer lipid membrane are called Gram-positive bacteria. The bacteria that have a thin layer of peptidoglycan and an outer lipid membrane are called gram-negative bacteria.

Gram-positive bacteria do not have an outer lipid membrane and hence they retain the crystal violet in the thick peptidoglycan during gram staining and it is fixed by iodine.

The outer lipid membrane that is possessed by the Gram-negative bacteria does not allow them to retain the crystal violet and hence only the counterstain safranin is visible in the gram staining method.

The technique of Gram staining was developed by the bacteriologist Hans Christian Gram in 1884. While this method cannot tell the specific strain of a bacteria, it can be used as a quick and easy way for narrowing down the basic criteria of distinguishing the bacteria among the two main groups.

Therefore, knowing whether a bacteria is gram positive or gram negative will help to understand the kind of infection it may cause and thus help in determining the kind of antibiotic it needs.

2.) during dehydration synthesis a water molecule breaks apart two monomers

3.) during dehydration synthesis and enzyme joins two monomers water is a byproduct

4.) during hydrolysis, a monomer breaks apart into two polymers,water as a byproduct ​

Answers

The answer is 3. During dehydration synthesis and enzyme joins two monomers water is a byproduct

The true statement is that during dehydration synthesis, an enzyme joins two monomers and water is a byproduct.

WHAT IS DEHYDRATION SYNTHESIS:

Dehydration synthesis is a reaction that involves the joining together of two or more smaller molecules to form a much larger and complex molecule accompanied by the release of water (H20).

During dehydration synthesis, the hydrogen (H) of one monomer combines with the hydroxyl group (OH) of another monomer releasing a molecule of water.

An example of dehydration synthesis is the reaction of glucose molecules to form larger polysaccharides.

how is sound recorded

Answers

Answer:

Sound is made up of waves in the form of vibrations in the air. Or you can use the signal to record the sound on magnetic tape. This works by a similar process of moving a magnet, but that magnet causes a magnetic tape to gain magnetization in patterns that represent the sound.

In a digital recording system, sound is stored and manipulated as a stream of discrete numbers, each number representing the air pressure at a particular time. The numbers are generated by a microphone connected to a circuit called an ANALOG TO DIGITAL CONVERTER, or ADC.

Explanation:

Answer:

sound is made up of waves in the form of vibrations in the air, and can be detected by the human ear. Using magnets analoque technology takes sound waves and turns them into electrical pulses. When a metal conductor is moved inside the magnetic field an electric current is produced in that wire.

Answers

Answer:

Animals are consumers and they all depend on plants for survival. Some eat plants directly, while others eat animals that eat the plants. In turn, some plants depend on animals to help spread their seed. Decomposing animal carcasses can also provide nutrients for plants to grow.

Plants and animals depend upon each other as mutual interdependence is must for their survival. Plants provide shelter for animals and they make oxygen for the animals to live. When animals die they decompose and become natural fertilizer plants. Plants depend on animals for nutrients, pollination and seed dispersal

balance the following chemical equation making sure to apply the principle of the law of conservation of mass​

Answers

Answer:

2Zn+ 4HCl=2ZnCl2 +2H2

CH4+2O2=CO2+2H2O

Fe + 3NaBr=FeBr3+3Na

The balanced chemical equations are given below:

[tex]Zn + 2HCl[/tex] → [tex]ZnCl_2[/tex] + H2. [tex]CH_4 + 2O_2[/tex] → [tex]CO_2 + 2H_2O[/tex]. [tex]Fe + 3NaBr[/tex] → [tex]FeBr_3 + 3Na[/tex].

What do you mean by Chemical equation?

Chemical equations may be defined as an illustration of a chemical reaction by using symbols and the amount of substance used in the reactant to form a desirable product.

In the first reaction, two atoms of hydrogen are there on the product side while only one is there is the reactant side, so to balance them, you put 2HCl, the reaction is balanced now.

In the second reaction, four atoms of hydrogen are there on the reactant side while only two are on the product side, so to balance them you put 2H2O on the product side, now balance the oxygen atom and put 2O2 on the reactant side. The reaction is balanced now.

In the third reaction, bromine has three atoms on the product side, to balance them you need to put 3NaBr on the reactant side, now to balance sodium atoms put 3Na on the product side. The reaction is now balanced now.

The principle of the law of conservation of mass states that mass is neither be created nor destroyed in chemical reactions.

Therefore, the balanced chemical reactions are described above.
