Good view from this hilltop; chilly and windy. We rested to catch our breath, then collected samples. Rocks are visible everywhere. There are boulders, cobbles, and pebbles of many sizes ans shapes mixed together. These surface rock fragments are composed of metamorphic rock sitting on the limestone bedrock. The teacher showed us parallel scratches in the bedrock. I saw almost no soil.
It is rocky and the stream bank is steep. Where we are standing, we can see a waterfall and rapids. It is cool by the water. From the streambed we collected pebbles and cobbles - some red, some white, others a mixture of many colors. The streambed is full of rocks of all sizes. The teacher warned us to be careful of the strong stream current.

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.

The oxidation of glucose to two molecules each of pyruvate, ATP, and NADH is called ________ and occurs in the ______.
Answer:
1. Glycolysis
2. Cytoplasm
Explanation:
This question is describing the process of cellular respiration. Cellular respiration, which is the process by which organisms obtain their energy (ATP), occurs in stages. The first stage undergone by all living cells is called GLYCOLYSIS.
IN GLYCOLYSIS, glucose molecule (from digested food) is broken down via oxidation in the CYTOPLASM of the cell, into two molecules each of pyruvate, ATP, and NADH. The pyruvate proceeds to the other stages of cellular respiration.
students are measuring the rate of enzyme activity. the graph below shows the rate of enzyme action as they increase the temperature. what is one possible reason the enzyme is less effective at high temperature

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.

Explain how DNA determines the structure of proteins
Answer:
Explanation: The sequence of bases in a DNA molecule can determine the order of amino acids in a protein molecule. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene .

Groups of three bases called triplets represent different amino acids. This has the basis of the genetic code . A sequence of the bases (genetic information) on DNA that codes for a protein has been called a gene.
What is DNA?DNA has been also known as the deoxyribonucleic acid and it has been basically composed of two polynucleotide chains and by the nature it has been a polymer. The polynucleotide chains can be folded around them with each other to form a coiled or the structure which has double helical and it has been consist of the genetic material along with the genetic information which has very much essential for proper body functioning, reproduction, growth, and other necessary activity of the body.
The the main objective of the DNA has that it has been containing genetic material which has to plays an important role in the survival of life as it has been consist of the instructions that has been required for the survial of life. The main constituent of the DNA or DNA has made up of the nucleotides. There are mainly three types of the DNA and these are A DNA, Z DNA, and B DNA. DNA consist four chemical bases and these are adenine, guanine, thymine, and cytosine.
Therefore, Groups of three bases called triplets represent different amino acids. This has the basis of the genetic code . A sequence of the bases (genetic information) on DNA that codes for a protein has been called a gene.
