Answer:thanks for points
Explanation:
suggest why digestion (the breakdown of large macromolecules) is largely performed by extracellular enzymes
Answer:
Enzymes speed up the breakdown of macromolecules in food to small molecules
Explanation:
During digestion, the macromolecules that make up food are hydrolyzed by digestive juices to molecules of a size that allows their absorption through the lumen of the tract. In this way, proteins are divided into amino acids, carbohydrates into glucose and other monosaccharides, and fats into glycerol and fatty acids. Digestion and absorption take place mainly in the small intestine.The production of extracellular enzymes that, once released into the medium, degrade the substrate and then allow their diffusion / transport.

A)All variations are adaptations, but not all adaptations come from variations
B)All adaptations are variations and all variations help organisms survive
C)Variations result from adaptations organisms make to the environment
D)Adaptations result from variations only if they help an organism survive
Answer:
B
Explanation:
Adaptations result from variations that help an organism to survive better in the environment. Option D is correct
Adaptation:
It is the physical changes in the organisms that increase the chance of survival.
Variation:
They are the traits that are found in the population that are caused by
genetic mutation.
For example- Coat color of Rabbit:
If it is brown color this can help rabbit to hide himself, but there are other colors also that are variation.

Answer:
Brainly's inappropriate language check is messing me up
Explanation:
Answer:
Hom.ozygous Dominant: SS, BB
Heterozygous: Ss, Bb
Homo.zygous Recessive: ss, bb
Explanation:
Every trait has "two alleles." These determine the characteristics of an organism. Homo.zygous alleles are classified into either "dominant" or recessive." It consists of two identical alleles. Heterozygous alleles means two different types of alleles.
A homo.zygous dominant means having two alleles of "smooth" hair (SS) or having two alleles of "black" hair (BB).
A homo.zygous recessive means having two alleles of "curly" hair (ss) or having two alleles of "chestnut" hair (bb).
A heterozygous is a combination of a dominant allele and a recessive allele. One allele for smooth hair and another allele for curly hair (Ss) or one allele of black hair and another allele for chestnut hair (Bb).
a layer of water just under a frog's skin captures oxygen from air or water and delivers it to blood vessels at the skin's surface.how might this function relate to the fact that frogs are very sensitive to environmental pollution
Answer:
Frogs breathe through water through their skin. This means their entire skin is their respiratory system in a way. If they submerge themselves in dirty and impure water, they'll become very easily sick and die.
Frogs breathe through their skin into the water. This implies that, in a sense, their entire epidermis acts as their respiratory system. They will quickly get sick and die if they immerse themselves in contaminated water.
What is respiratory system?Such respiration occurs through four to five pairs of gills while a tadpole is in its larval stage.
Blood veins are scattered throughout the gills, which use diffusion to take in oxygen. Blood's hemoglobin and oxygen mix to create oxyhaemoglobin, which travels to tissues.
Cicatricial respiration is the term for breathing through the skin. It occurs in water and during aestivation and hibernation, when the need for oxygen is minimal and metabolism is low. Through the blood capillaries, where oxygen combines with hemoglobin, skin absorbs oxygen dissolved in water.
Therefore, Frogs breathe through their skin into the water. This implies that, in a sense, their entire epidermis acts as their respiratory system. They will quickly get sick and die if they immerse themselves in contaminated water.

3. What can you say about the general relationship of the charge of the anion to the subscript of the cation?
Answer:
Cations are positively charged ion while anions are negatively charged ions formed by loosing and gaining of electrons respectively. Transition metals are metals in the middle of the periodic table with multiple oxidation states. The charge on the transition metal is equal to the oxidation state which varies from +1 to +7. The charge of transition metal can also be determined in neutral compound as long as one knows the charge or the oxidation state of the other atom in the compound. The charge of transition can also be determined in the case of neutral complexes where the transition element has combined with other atoms to form molecular complexes that are either positively or negatively charged, e.g. MnO4-. Lastly Neutral transition metal compounds which are soluble in water have a charge of +3 or less than+3.
Cations are positively charged particles and anions are negatively charged elements.
What are cations?Anions are negatively charged ions created by losing and receiving electrons, whereas cations are positively charged ions. Transition metals are middle-of-the-periodic-table metals with a variety of oxidation states.
The oxidation state, which ranges from +1 to +7, is equivalent to the charge on the transition metal. As long as one is aware of the charge or oxidation state of the other atom in the compound, one may also determine the charge of a transition metal in a neutral compound.
When the transition element has joined with other atoms to form neutral molecular complexes that are positively or negatively charged, such as MnO4-, it is also possible to detect the charge of the transition.
Therefore, Cations are positively charged particles and anions are negatively charged elements.

Explanation:
Which of the following is the mean number per cross of F2 generation offspring that are the result of crossing over
Answer:
2.2
Explanation:
Since all of the mice in the F1 generation are heterozygous for both traits, they contain a copy of each on separate chromosomes. (AB on one from parent 1 and ab on the other from the parent 2.) If these chromosomes split away from each other without crossing over, the F2 offspring can ONLY by AABB or aabb. This means that any heterozygous combinations are the result of crossing over and must be counted. When all are counted, we get a total of 11, or 2.2 per cross.
To calculate the mean number per cross of the offspring that result of crossing over, we need to make an addition of individuals that result from crossing-over, and divide the result by the number of crosses. The result is 2.2.
---------------------
According to the statement, crosses were as follow
Cross 1) Between two true-breeding
Parentals) LLBB x llbb
F1) 100% LlBb
Cross 2) Between two dihybrids
Parentals) LlBb x LlBb
The results of the F2 are
Phenotype Cross1 Cross2 Cross3 Cross4 Cross5
Long-Black 6 5 5 6 7
Long-White 1 1 0 2 2
Short-Black 0 2 1 1 1
Short-White 2 3 3 2 2
If there is no crossing-over, offspring will have the same chromosomes as parentals, which are Long-Black (LB) or Short-White (lb), because these chromosomes separate without interchanging segments.
However, if there is crossing over, these chromosomes interchange segments, and the result is Long-White (Lb) and short-black (lB).
So now, we need to count how many individuals from the F2 are a result of crossing-over.
Phenotype Cross1 Cross2 Cross3 Cross4 Cross5 Total
Long-White 1 1 0 2 2 6Short-Black 0 2 1 1 1 511
Eleven individuals result from crossing over. But we need to calculate the mean number per cross.
So, since there are 5 crosses, we need to divide the total number of individuals that are the result of crossing over by the total number of crosses.
total number of individuals = 11total number of crosses = 5Mean number per cross of F2 generation ⇒ 11/5 = 2.2
The mean number per cross of F2 generation offspring that are the result of crossing over is 2.2

Subscripts in a molecular indicate how many of each type of can be found in that molecule.
Answer:
A subscript is used only when more than one atom of a given type is present.
Explanation:
Molecular formulas are written with an index in the lower right corner. The index indicates the total number of atoms of one chemical element that is part of a molecule.
In the molecular formula of a compound, the coefficients can be different and that means that we have a different number of molecules of the same compound, but the indices cannot be different, because then it is no longer the same compound.
