Why do you think in the table below, Adenine and Thymine have almost the same number – but not exactly?

Nucleotide

# found in genome

Adenine

701,234,142

Guanine

803,127,160

Cytosine

803,127,162

Thymine

701,234,146

Answers

Answer 1
Adenine pairs with thymine and Guanine pairs with cytosine. The numbers are not exactly the same because of the mutations that happen in DNA. Some of the DNA could be broken off or put somewhere else in the gene that would throw everything off, nothing is perfect. However in a perfect world, both adenine and thymine would have the same numbers.

Answers

Answer:

The suspicion of the students are very correct. Millipedes prefer damp environments. They need water moisture to survive.

Explanation:

Millipedes are known as arthropods. An Arthropod is an animal without a spinal vertebra, which possesses a segmented body, paired jointed appendages, and an exoskeleton.

They are found to be very ardent and quicker at recycling natural waste than animals and plants.

Without adequate moisture, Millipedes can die within 48 hours.

What is the chemical reaction that lactase catalyzes?

Answers

Answer:

galactose and glucose

Explanation:

Lactase catalyzes the hydrolysis of the glycosidic bond in the disaccharide lactose, releasing galactose and glucose hope this worked :)

The chemical reaction that is catalyzed by the enzyme lactase is the breakdown of lactose into glucose and galactose. The reaction is as follows:

Lactose → Glucose + Galactose. (in the presence of Lactase).

What is a Chemical reaction?

A chemical reaction may be defined as a process through which one or more substances known as the reactants are significantly transformed into one or more different substances known as the products in the presence of enzymes of energy.

Lactose is a type of disaccharide which dissociates into glucose and galactose. It is similar to maltose which in presence of an enzyme maltase gives two different compounds of glucose and sucrose in presence of an enzyme sucrase converts into glucose and fructose.

Therefore, the chemical reaction that is catalyzed by the enzyme lactase is the breakdown of lactose into glucose and galactose.

Answers

I think either neutral ph or more enzyme
I think it’s. 1 (slight increase in temperature) cuz at extremely high temperature enzymes get destroy so it’s not (5) at all
Or it can be (4) cuz conc of substrate is directly proportional to the rate of enzyme but at high concentrations of substrate it slows the reaction of enzyme.

Answer:

The correct answer is - bogs.

Explanation:

Bogs or boglands is a wetland that is made up of dead organic matter such as dead plants or parts of the plants like mosses, majority time it is a thick carpet of sphagnum moss. All these form spongy peat which is stagnant.

Most of the water present in this wetland comes from rainfall instead of runoff or streams from the groundwater which makes it a wetland with a shallow area of water-saturated soil. This wetland is known for its less photosynthesis.

Answers

Answer:

Increasing  carbon dioxide  concentration  increases the  rate of  photosynthesis  as carbon  dioxide (CO2) is a limiting factor.

Explanation:

Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.

The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.

Chlorophyll, cell wall and vacuole, chloroplasts, and mitochondria are used to fill in the blanks.

What are cell organelles?

An organelle is a subcellular structure that, like an organ, has one or more specific jobs to do in the cell.

The organisms that comprise the pigment chlorophyll convert the energy from light into chemical energy that can be stored in the form of sugars through the process of photosynthesis.

The cell wall and vacuoles found in plant cells aid in the preservation of shape and integrity.

Chloroplasts are plant organelles that work to store pigments and food. It stores pigment, specifically chlorophyll, which converts light energy into chemical energy.

The mitochondria convert food into usable energy through the process of cellular respiration. The mitochondria, which are found in all plants and animals, are thought to be converters.
