Consider the following scenario: In a muddy lake environment, some fish have brown scales. Most fish, however, have silver scales. Predators have a harder time seeing the fish with brown scales. Which term best describes the brown scales?​

Answer:

We have to balance chemical equations because you need to satisfy the law of conservation of matter. That states that matter cannot be produced or destroyed in a closed system. The law of conservation of mass governs the balancing of a chemical equation.

Answer:

I think you meant how?

Explanation:

but always you balance a chemical equation by looking at how many atoms you have for each element. For example we have the chemical equation Na + Cl2----> NaCl

so there's 1 Na atom

there's 2 Cl atoms

and for the product side

there's 1 Na atom

there's 1 Cl atom

TO BALANCE THIS you have to make the reactants side equals the product side by ADDING COEFFICIENTS.

so it would be 2Na + Cl2 ---> 2NaCl

Answer:

Metabolic pathways in monarch butterflies are as follows:

Explanation:

They convert sugar which they obtain from nectar into fats that they store as source of energy. Monarch have a little layer of fatty tissues which aid in conversion of Sugar in to fat.

They consume the stored fat during reproduction. A lot of fat is eventually converted to eggs and some of it is used to provide energy just to sustain the reproductive butterflies.

During winter season, when their metabolic is low they consume energy by converting stored fat into sugar called Trehalose.  The conversion of fat also releases little water which help them to survive during winter.

1) Glycolysis:

2. Kreb's Cycle:

The acetyl-CoA formed enters into the Kreb's cycle by condensing with oxaloacetate. In Kreb's cycle acetyl-CoA is completely oxidised to give carbon dioxide in eight enzymatic reactions. During Kreb's cycle NADH, FADH2 and one molecule of GTP is produced and oxaloacetate is regenerated to continue the cycle.

3. Oxidative Phosphorylation:

The NADH produced in the glycolysis and Krebs cycle and FADH2 produced during Krebs cycle are now oxidised to generate proton gradient across the inner mitochondrial membrane. This gradient is generated when the electrons from the reduced NADH and FADH2 are transported in the electron transport chain(ETC), and are finally accepted by the oxygen.

When the electrons are picked up by the complexes of the ETC they pick protons from the matrix. When the electrons are transferred to next complex the protons are transferred to the inter-membrane space. In this way a proton gradient is generated across the innner membrane of the mitochondria.

This proton gradient is used by the complex V of the ETC. This complex is the enzyme ATP Synthase. This enzyme complex is located in the inner mitochondrial membrane. When the protons flow back from the inter-membrane space into the matrix along the concentration gradient , they move through the channel in the ATP Synthase Complex. When these protons flow through this complex it catalyzes the phosphorylation of ADP to give ATP, the energy currency.

The fructose component of the sucrose is first converted into glycogen and then broken down to give glucose-1-phosphate, which enters into glycolysis.

Sucrose cannot enter the pathway of glycolysis as such. It is first hydrolysed to glucose and fructose as described above along with the path way.

Answer:   Meiosis and mitosis are both cell division cycles that result in daughter cells. Meiosis occurs in the gametes, while mitosis occurs in all non-gamete cells. Meiosis also results in two cell division rounds, whereas mitosis only has one cell division round.

Answer:

glucose is a sugar, therefore cannot make proteins

Explanation:

Answer:

Due to its thin width and elasticity.

Explanation:

A jumping rope could be used to model the cell membrane of a plant cell because of their elasticity that acts like cell wall or cell membrane of the cell. Just like a cell wall or cell membrane which is the outer covering is thin in width and has the ability to elasticity so the jumping rope is also used in the model due to its elasticity and thin width so that's why we can used it in the cell model.

1.  A reexamination of HIV seroconversion studies suggests that condoms are 90 to 95% effective when used consistently, i.e. consistent condom users are 10 to 20 times less likely to become infected when exposed to the virus than are inconsistent or non-users.

The main reason why has the Ugandan government pushed Abstinence as a means of combating the spread of HIV/AIDS is: the people for whom the propaganda is done are mostly children above 10, who tend to start having sx at an early age.

The ABC strategy is credited for bringing the HIV/AIDS epidemic under control in Uganda. By promoting abstinence, being faithful, and condom use, safe(r) behaviours have been identified that are applicable to people in different circumstances.  Because the people for whom the propaganda is done are mostly children above 10, who tend to start having sx at an early age.

Thus, this could be the answer.

Answer:Club mosses are low evergreen herbs with needlelike or scalelike leaves. Many species have conelike clusters of small leaves (strobili), each with a kidney-shaped spore capsule at its base. The plants are homosporous, meaning they produce just one kind of spore

Explanation:Although they lack true veins, many species of mosses have long narrow cells in their stems, the midribs of their leaves, and their rhizoids (root-like plant tissue) that can be considered evolutionary precursors to true veins. Vascular plants with true veins include the clubmosses, ferns, and flowering plants.

Answer:

Explanation:

After amylase act on carbohydrates, the chyme pass through the oesophagus down to the dudoneum in the small intestine. Amylase also continue to break it down into disacharrides and enzymes like maltase, sucrase and lactase are released to further break it down into maltose, sucrose, and lactose then finally glucose, a way it can be absorbed easily by the epithelial walls.

The digestion of lipids and protein begin in the dudoneum of small intestine.

Trypsin act on protein and break it down to peptides. Peptidase is then released and break it to single chain peptides bond. In the small intestine, dipeptidases break it down into amino acids easily absorbed by the epithelial walls.

The bile in the gall bladder produce enzyme called lipases which breakdown lipids and make it to undergo emulsification.

Answer:

Zero

Explanation:

Because in a situation whereby both parents are carriers of an autosomal recessive condition there is a 1 in 4 chance of them having an affected child.

Hence, given that these two normal parents have already had one affected child with the autosomal recessive disease homocystinuria. There is ZERO chance of having an affected child in the next three kids they will be having.

During the drought, there was as scarcity of food and resources and the

birds which have larger beaks has an advantage over other types. This was

as a result of their ability to find food in more areas.

Birds with long beak were able to crack seeds which were large and stronger in size which give them the advantage over others.

Answer:

B) CFU/mL calculations would not be accurate

Explanation:

In microbiology CFU is the acronym for Colony Forming Unit, which indicates the number of bacteria or fungi capable of multiplying under suitable conditions. In this case, CFU/mL indicates how much bacterial or fungal cells, susceptible to reproduction, exist within 1 mL of a culture solution.

When this solution is used, to make a dilution or other laboratory activity, it is important that it be resuspended, that is, mixed, as the bacteria or fungus cells can accumulate in the bottom or surface of the substance, changing the value of CFU/mL and causing inaccurate dilutions if used. When resuspended, the substance presents the appropriate value of CFU/mL, ensuring that the dilution is accurate and effective.

D. Water is the most abundant atom in Earth’s atmosphere.

Explanation:

An atom can be defined as the smallest particle of an element (e.g., oxygen, hydrogen, etc). Water is a molecule (H2O) because its atoms are connected by molecular bonds (i.e., water is not an atom). Water is the most abundant molecule on the Earth's surface which covers more than 70 percent of the world's surface. A water molecule contains one oxygen (O) and two hydrogen (H2) atoms which are connected by covalent bonds. Water is also a compound known as a diatomic molecule, i.e., a molecule composed of two atoms of the same type.
