Answer:

Some animals have adapted to life in the taiga by hibernating when temperatures drop. Other animals have adapted to the extreme cold temperatures by producing a layer of insulating feathers or fur to protect them from the cold. In some instances, the adaptation of a seasonal change in color of feathers or fur protects the animal from its predators.

Answer:

The more characteristics organisms share, the more closely related they are.

Shared characteristics can exist among organisms that belong to different species

Explanation:

A shared character can be regarded as a character that is shared by two lineages.

The statements that best describe shared characteristics

The classification of all living entities is based on extremely basic, universal  traits.

Each group's organisms are subsequently subdivided into smaller groupings.

Each bigger group is divided into smaller groups based on more detailed similar shared characteristics.

Answer:

4. According to what is observed in the diagram, the maltose (substrate) binds to the maltase (enzyme) to obtain glucose molecules (product), in a process of hydrolysis of the maltose.

5. Three factors that can affect intestinal maltose activity - slowing it down or stopping it - are temperature, pH and substrate depletion.

Explanation:

4. Enzymes, such as maltase, have the function of making a reaction faster and decreasing the activation energy. Maltase is responsible for breaking down a maltose molecule, a dimer, into two glucose monomers, which is a hydrolysis reaction of the bonds that hold glucose molecules together.

5. There are several factors that can cause the decrease or cessation of the activity of an enzyme. Enzymes are activated when substrate is available and work best under ideal temperature and pH conditions. When there are alterations of these factors, the enzyme will reduce or stop the reaction in which it intervenes.

Answer:Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.

A star can be defined as a giant celestial (astronomical) object that is made up of a luminous sphere of plasma bounded together by its own gravitational force.

Generally, a star consists of two (2) main interstellar hot gas and these are:  

I. Hydrogen (H).

II. Helium (He).

Some of the examples of a star are;  

A nebula simply refers to a low-density cloud of interstellar hot gas (hydrogen and helium) and dust.

Basically, a nebula is needed for the creation or formation of a star.

Hence, the role of a nebula in the life cycle of a star include the following:

Stage 1: The temperature increases in the center of a nebula, thereby, causing the small nuclei of atoms to fuse.

Stage 2: The nebula gets hotter and brighter as the nuclear fusion sets off a chain reaction while providing enough energy to turn the nebula into a star.

Explanation:

Reading frame is a sequence of codons determined by nucleotides that are read in groups of three from a specific translation start codon, that is, it is a linear sequence of codons or triplets in a nucleic acid. It is one of three possible reading alternatives of a nucleotide sequence of a series of triplets, this means that, in a double-stranded DNA molecule, there are 6 possible directions in which reading frames can be opened; three in the forward direction and three in reverse.

Answer:

Molecules move up the concentration gradient in facilitated diffusion, which requires ATP to be used as molecules naturally move from high to low concentration

Explanation:

: )

Molecules move down their concentration gradient in facilitated diffusion through channels of proteins.

For most molecules, movement through the membrane, with a significant rate, is only possible by the presence of transporter proteins (integral membrane proteins, which recognize substances with a high specificity, accelerating their translocation) or channels of proteins.

Transport proteins allow the facilitated diffusion of molecules, moving them along the free energy gradient (concentration gradient, charge gradient, or both), in the direction of thermodynamic equilibrium.

When a carrier protein binds to a solute, the protein changes shape in such a way that it carries the solute to the other side of the membrane.

Facilitated diffusion is similar to simple diffusion, since the molecules move from a region of higher to a lower concentration of solutes.

For example, by facilitated diffusion, chlorine ions move down their concentration gradient into the cell through chlorine channels.

Therefore, we can conclude that many molecules are assisted by transporter proteins for their diffusion through the plasma membrane, a process known as facilitated diffusion, where the molecules descend through their concentration gradient.

Answer:

Infiltrate rate decreases and also water quality.

Explanation:

There is adverse effect of erecting buildings and concrete pavement on the recharge of aquifers and the quality of the water because the water is unable to infiltrate inside the soil due to concrete floor and the recharging of aquifers is not possible. These buildings and concrete pavements also reduces the quality of water due to degradation of sediments present in the building with the passage of time.

Answer:

Mutations are errors in codons caused by changes in nucleotide bases. Some mutations may not have much effect. For example, if the codon GAA becomes the codon GAG, because the genetic code is degenerate, the codon will still code for the amino acid glutamate. Such ineffectual mutations are called silent mutations. Some mutations, however, can have a huge affect on coding for amino acids, which can in turn affect what proteins are produced, which can have a profound effect on cellular and organismal function.

Answer:

The fossils that provide information on the formation of an oxygen-rich atmosphere are the stromatilites from the Precambrian era. These are layered and columnar fossils consisting mainly of cyanobacteria which were the original life form back then. These bacteria took in carbon dioxide and produced oxygen by photosynthesis as early as 2.5 billion years ago (the earth is about 4.5 billion yrs old).
