Help me please !!!!!!!!!

Answer:

Explanation:

Biosphere is the portions/regions of the earth (including land, sea and atmosphere) where living organisms exist. From the picture attached, it can be seen that there are living organisms in the hydrosphere (fishes), geosphere (plants) and anthrosphere (human).  The entire system should have been labelled biosphere and not atmosphere.

NOTE: Atmosphere is an empty air space surrounding/around the earth (or other celestial body).

Answer:

I would say B because they are trying to see which one the prefer

Answer:

Nucleic acids - macromolecules containing hydrogen, oxygen, nitrogen,

carbon and phosphorus and are associated with organism's genetic code.

Monomer (single) units of nucleic acids are called nucleotides. One

nucleotide consists of a 5-carbon sugar , a phosphate group and a nitrogen

base.

Answer:

The five piece of lab equipment that we will use are

1. Preserved frog specimen

They are safe to use and are not subject to hazardous materials regulations or disposal restrictions.

2. Dissection tray

They are essential when analyzing internal structures and component related functions. Compatible with lining waxes used to provide unadulterated dissecting pin surfaces or including odor absorbent pads, pans allow animals to be securely held in place.

3. Scalpel

They are used to make cuts into the body. This is a very sharp instrument and comes in various sizes for different types of cuts and surgeries. Most blades are made of either carbon or stainless steel.

4. Dissecting scissors

They are used for fine dessection ,making incisions, cutting apart tissues and removing different organs.

5. Forceps

They are used to handle tissues and other materials and also to manipulate needles and other instruments whilst operating. They are commonly used for grasping fine tissue and blood vessels or soft tissue dissection.

Answer:

11 males, 25%  

Explanation:

Eleven of the 44 males in this study are taller than 175 centimetres, which makes it one fourth of the total that is 25%. See below:  

simplify the fraction [tex]\frac{11}{44}[/tex]  

= [tex]\frac{1}{4}[/tex]  now multiply it by 100 to convert to a percentage value.

= 25%

Answer:

Also called the vacuolar membrane, the tonoplast is the cytoplasmic membrane surrounding a vacuole, separating the vacuolar contents from the cell's cytoplasm.

Answer:

Answer:

This question lacks options, the options are:

A) Deletion

B) Duplication

C) Inversion

D) Insertion

The correct answer is Insertion mutation

Explanation:

Mutation refers to changes that occur to the nucleotide sequence of a gene or DNA. Mutation produces different effect in the mutated organism and is classified based on how it occurs. Mutations can be deletion, insertion, duplication, inversion etc.

Based on the description of the mutation that occured to the bacterium sequence, it is an INSERTION MUTATION. An insertion mutation is a kind of mutation in which extra nucleotide bases are added to the original sequence. This is the case of this bacteria sequence, which was previously found to contain: ATCGGGATCCT.

After few generations, nucleotide bases "GGG" i.e three Guanine bases has been added to the sequence to give a mutated sequence: ATCGGGGGGATCCT.

Answer:

Duplication

Explanation:

Answer:

C. Dependent variable

Explanation:

The temperature of the air in each box is the dependent variable because it is the variable that is affected/changed by the IV

The independent variable is the type of material of the box, because it is the variable being changed by the experimenter.

Answer: Dependent variable

Explanation: I took the test :>

Answer:

For example, the building block of carbohydrates is sugar, the building block of lipids is fatty acids, the building block of protein is amino acids and the building block of nucleic acids is the nucleotide.

hope it helps:-)

Answer:

Sporangiophore

Explanation:

a fertile hypha that bears a sac-like structure called a sporangium

Answer: sporophyte, gametophyte, alternation of generation

Explanation:

Alternation of generation is a kind of life cycle seen in plants and algae in which the diploid asexual and haploid sexual stages exist. A sporophyte is multicellular and diploid which is an asexual stage. It produces the haploid spores through meiosis. The haploid spores germinate to produce haploid gametophyte. The gametophyte produces gametes by the process of mitosis.

Answer:

regulating blood sugar levels

Explanation:

The primary function of the insulin hormone is to convert the excess glucose in the blood after a meal and store it for later. Glucose gets converted to glycogen, which is a compact molecule ideal for storage. When the body is need of energy, this glycogen is broken down to make up for the lack of glucose present in the blood.

Answer: the maintenance of homeostasis within the body system.

Answer:

Water dissolves many biomolecules, because they are polar and therefore ... that acts as a solvent and surrounds a solute species) with a water solvent; also ... a substance capable of dissolving other polar molecules and ionic compounds. ... are either polar or charged, water readily dissolves these hydrophilic compounds.

Explanation:

Answer:A robot is a machine. It is often, or almost always, automatic, which means that it is able to perform activities on its own without the aid of external variables, like humans. It moves in the way that it was originally programmed, or designed to act. These actions are described as ‘intents’ of its own. For example, a robot that is designed to play ping pong will really move like a ping pong player, compared to a robot that is just used for plain surgical operations.

‘Robot’ is also a word that refers to the sum of all the groups of robots, comprised of the physical robots and the virtual robots (as in software). In the case of the latter, these are called bots.

Human beings are also highly social individuals. They survive alongside other people in groups called communities or families. They are capable of forming relationships, and generating complex feelings, or emotions such as love.

1. Humans are organic beings, while robots are not.

2. Humans are far more complex and superior to robots in almost all aspects.

3. Humans are highly social beings compared to robots

Explanation:

Answer:

The distance between Lawrence, Kansas and Nashville, Tennessee is 501.74 miles. So they are really far apart.

The location of Lawrance, Kansas is:

Latitude: 38.9560 Longitude: -95.2520.

And for Nashville, Tennessee is:

Latitude:  36.174465, Longitude:  -86.767960.

So while the Latitudes are similar, the longitudes are not, and this is why you can see that the geography of each place is different.

Answer:

Because some effects will occur.

Explanation:

The positive test which was the result for the organic molecules for the water sample showed that there is some change occurs in water sample by adding of organic molecules due to which the results of the test comes positive. If there is no change occurs in the water sample by adding some organic molecules so the results will come negative which means no effect.

Answer:

Explanation:

Biology can be referred to as the study of life.

One question that can be asked about the study of life is "if green plants excrete". Since excretion is one of the characteristics of living things, one question that could be intriguing is the possibility of plants performing this process.

This question can only be answered be answered/verified by a scientific experiment because the process cannot be observed/determined with the naked eye.

Explanation:

Hey, there!!

The answer is option A. (Ants)

As herbivorous are those organism which only consume various type of plants.

So, all are consumed by herbivorous expect ants as it is an insect.

Answer:

prokaryotic cells do not have a nucleus or membrane bound organelles.They also have small rings of double-stranded extra-chromosomal DNA called plasmids.

Answer:

The correct answer is "photorespiration".

Explanation:

Photorespiration is a process in plants, where molecular oxygen is taken in a light-dependent  manner. Photorespiration is often considered a wasteful pathway because it competes with the Calvin cycle, which is much more efficient. In C3 plants the conservation of water promotes photorespiration. This occurs when the C3 plants close its stomata because the environment its too hot, or the carbon dioxide concentration drops to about 50 ppm.
