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).

It is cool in the shade, and the rock cliff above us still has some ice on it from winter. The rocks we are sitting on have sharp edges. Rock fragments at the
bottom of the cliff are the same color as the cliff. Our teacher warned us to watch out for falling rocks.

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.

How does the sun power the carbon cycle
Answer:
The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun.
Explanation:
Where does the carbon in glucose end up at the end of cellular respiration?
a. it stays in glucose
b. it is released into the air as carbon dioxide
c. it disappears
Answer:
it is released into the air as carbon dioxide
Answer:
B
Explanation:
Through the process of Cellular Respiration, a organism inhales and exhales, and the carbon is then turned into CO2, or Carbon Dioxide,
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.

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.
Which of these increases the level of carbon dioxide in the atmosphere?
A. Driving a car

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.
