How does high specific heat help aquatic organisms?
Answer:
Explanation:
Due to its high heat capacity, water is used by warm blooded animals to more evenly disperse heat in their bodies; it acts in a similar manner to a car's cooling system, transporting heat from warm places to cool places, causing the body to maintain a more even temperature.
A river that is mature would be: *

B. curved, slow flowing and would have more erosion on the outside curve
When a trait is shown and at least one letter is upper case.
A) dominant
B) recessive
C) trait
D) allele
Answer:
maybe trait?
Explanation:
dunno lol
Answer:
When a trait is shown and at least one letter is upper case, it is a dominant allele (option A).
Explanation:
In genetics the presence of a dominant allele - represented by a capital letter - is sufficient to suppress a recessive allele, expressing the dominant trait in the phenotype.
Dominance is based on allelic combinations of the genotype, which are expressed in the phenotype for a given characteristic:
Two dominant alleles (AA) express the only possible trait, dominant.One dominant allele and one recessive allele (Aa) show a dominant phenotype, as the former suppresses the latter. It is a hybrid or heterozygous.Two recessive alleles (aa) show a phenotype with the recessive trait.The other options are not correct, because:
B) Recessive is the allele that is only expressed in the phenotype when there is a pair in the gene.
C) Trait is equivalent to a characteristic.
D) Allele represents the different ways in which a gene is expressed.
Which of these is a benefit of naturally occurring forest fires? A) They spread the seeds of some trees. B) They allow the forest to become dense. C) They cause the forest canopy to thicken. Eliminate D) They allow ladder trees to entwine with large trees.
Answer:
A
Explanation:
Here, we want to pick which of the options is a correct answer to being the benefit of naturally occurring forest fires.
The correct answer is that they help to spread the seeds of some trees.
Naturally occurring forest fires ravages the forest and thus work with wind force. They proceed through the entirety of the forest from the point in which they start.
By moving from a particular point in the forest to another point in the forest, they allow for the process of mass movement to naturally occur.
By translocation from one point to another, they take the seeds alongside with them and thus allows for the dispersal of these seeds through the forest
Answer:
the correct answer is A

Explanation:
The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case? (3 points)
a) Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.
b) The two sides of a cell membrane face different environments and carry out different functions.
c) The molecular composition of the inner and outer layers of the cell membrane is determined by genes.
d) Proteins only function on the cytoplasmic side of the cell membrane, which results in asymmetry across the membrane.
Answer:
The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.
Explanation:
PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .
PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.
On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.
LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.
The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.
Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.
CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.
Hence , the correct option is B.

A landscaper is shopping for landscaping materials. She wants to use materials through which water flows easily. Which two materials should she choose? Clay and gravel gravel and loosely packed soil granite and rocks with cracks rocks with cracks and clay
Answer:
The correct answer is - Clay and gravel
Explanation:
Water can flow from the substance or material with greater porosity which is the number of pores resent in the particles of soil for easy exchange of water and gases.
Clay particles exhibit a higher amount of pores that permit the water to flow from it. Gravel allows water to pass from it as it is a loosely packed fragment of rocks

which of the following would be a quantitative observation
a. the attractiveness of the tail feathers of a male peacock is compared
b. butterfly wings are assessed to see which is the most orange in appearance
c. the height of radish seedlings is measured
d. the odor of different plants is compared to see which smells the worst
Answer:
c. the height of radish seedlings is measured
Explanation:
Quantitative measurements revolve around the quantity of things and exact measurements. The measured height of a radish seedling is the perfect example of that.
Memory technique:
Quantitative observations involve quantity (numbers).Qualitative observations involve quality (descriptions, features, i.e. color, smell, shape)Respiration is a series of enzyme-catalyzed reactions. Looking at the data below what is the optimum temperature
for the enzymes responsible for respiration?
Answer:
30C
Explanation:
One sign that a chemical reaction has taken place is the production of a gas. The more gas bubbles produced, the more reactions that the enzyme is catalyzing.
The highest number of gas bubbles are produced at 30C. The enzymes have the greatest activity in catalyzing chemical reactions at this temperature.
Therefore, this is the optimum temperature for the enzymes in this experiment.

Which pair of properties apply to both mechanical and electromagnetic waves?
A.
Both waves carry energy and refract
B.
Both waves are longitudinal and refract
C.
Both waves are transverse and carry matter from one place to another
D.
Both waves carry energy and do not need a medium to travel through
Answer:
A. Both waves carry energy and refract
Explanation:
There are two major types of waves viz; mechanical waves and electromagnetic eaves. Mechanical waves such as sound waves are waves that require a medium or matter to pass/travel through while electromagnetic waves like light waves do not strictly require a medium to travel i.e through vacuum.
Electromagnetic waves are transverse waves i.e their particles move perpendicularly to the direction of the wave while mechanical waves can either be transverse or longitudinal. All waves carry energy from one medium to another and are capable of refraction i.e. change of direction.
Therefore, both mechanical and electromagnetic waves carry energy and refract.

Which of the following is not a key ingredient in cloud formation?
particles. drizzle. water vaper. drop in air pressure
Answer:Drizzle
Explanation:
Clouds require water vapor, particles the vapor can condense around, and a drop in air pressure to form.
Cloud formation is a process that begins with a drop in air pressure. An ingredient that is not key in the formation of clouds is;
A. DrizzleDrizzle is not an important factor in the formation of clouds. Clouds are formed when water and ice are suspended in the air.
The process of cloud formation begins when the terrain is heated up by the sun.
Wind blows more around the areas of low pressure thus causing the rising of warm air which holds up water.
After some time, this air becomes condensed and falls down as rain.
Summarily, Drizzling is not an important part of cloud formation.
