As lactose approaches the active site of lactase, as shown in the image, which of the following occurs first?

The lactose molecule is broken into glucose and galactose.
Lactase shifts to its lowest free energy level to allow lactose to enter the active site.
Lactose creates a microenvironment as it approaches lactase to promote binding.
Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Answers

Answer:

There is no image attachment, however, this question can be answered based on general understanding of enzymes. The answer is:

Temporary bonding occurs between the active site and the substrate, causing a conformational change.

Explanation:

Enzymes are proteinous molecules that acts as catalyst in biochemical reactions by speeding up the rate of reactions. According to this question, lactase is an enzyme that acts on lactose sugar and breaks it down into its monomeric unit (glucose and galactose).

All enzymes possess an active site, with which they bind to their substrate. In this question, the lactose (substrate) approaches the active site of lactase (enzyme), what occurs first is that a temporary bonding occurs between the active site and the substrate, causing a conformational change in the shape of the enzyme.

Which of the following is NOT true about matter in the biosphere?
a) Matter is transferred in one direction through the biosphere. b) Biogeochemical cycles transform and reuse molecules. c) The total amount of matter decreases over time. d) Human activity does not affect the movement of matter

Answers

Answer:

c) The total amount of matter decreases over time.

Explanation:

The statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

The biosphere refers to the total of all ecosystems of the Earth.

The biosphere can be defined as a closed system in terms of matter because matter does not enter or exit.

In the biosphere, the total amount of matter remains constant over time, whereas the total amount of energy decreases over time.

This energy is lost in the form of heat when it spreads from the Earth's surface and outward into space.

In conclusion, the statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

1. A rabbit can cover a distance of 80 min 5 s. What is the speed of the rabbit?

Answers

I did 80 divided but 5. Which gave me 16 so the speed of the rabbit is 16 mph

Answer:

[tex]\boxed {\tt 16 \ m/s}[/tex]

Explanation:

Speed can be found by dividing distance by time.

[tex]s=\frac{d}{t}[/tex]

The rabbit travels 80 meters in 5 seconds.

The distance is 80 meters and the time is 5 seconds.

[tex]d= 80 \ m \\t- 5 \ s[/tex]

Substitute the values into the formula.

[tex]s=\frac{80 \ m }{5 \ s}[/tex]

Divide.

[tex]s= 16 \ m/s[/tex]

The rabbit's speed is 16 meters per second.

Un niño que ha enfermado de paperas o varicela, no desarrollará estas

II. en el primer contacto adquirió anticuerpos.

III. interviene la inmunidad Adaptativa, la cual presenta "memoria".

IV. su sistema defensivo está preparado frente a una segunda exposición

a. I y II son correctas

b. III y IV son correctas

c. II, III y IV son correctas

d. I, II y III son correctas.

Answers

Respuesta:

La respuesta correcta es la C, ya que II, III y IV son correctas.

Explicación:

Nuestro sistema inmunológico nos defiende de agentes patógenos que pueden enfermarnos, y está compuesto por dos tipos distintos de inmunidades: la inmunidad innata y la inmunidad adaptativa.

La inmunidad innata es aquella que reacciona primero cuando se presenta una amenaza, atacando a los patógenos de manera inespecífica gracias a mecanismos que ya existían antes de que se desarrolle la infección. Cuando se trata de inmunidad innata, nuestras principales barreras de defensa son la piel y las mucosas, y las células de la respuesta inmune de mayor relevancia son los neutrófilos, entre otras.

Por el contrario, la inmunidad adaptativa, es de respuesta tardía y puede actuar de maneras diferentes dependiendo de cuál sea el patógeno invasor. Hay dos tipos de inmunidad adaptativa, la humoral y la celular. De la inmunidad humoral participan principalmente los linfocitos B, que fabrican anticuerpos específicos; mientras que la inmunidad celular es llevada a cabo por linfocitos T. La ventaja que tiene la inmunidad adaptativa en comparación con la innata es que es específica, diversa, más eficaz, y POSEE MEMORIA.

Las células de la inmunidad adaptativa presentan la capacidad de "recordar" cómo el cuerpo actuó ante una amenaza en el pasado para poder llevar a cabo un plan mucho más eficaz. Esta es la razón por la que las vacunas funcionan: porque se le inyecta a los individuos una versión débil del patógeno (por ejemplo, del virus que causa la varicela) para que el cuerpo "aprenda" a vencerlo para cuando se encuentre con ese microorganismo en un futuro.

Family members have a widely varied genetic make-up that can be affected by specific mutagens.
Family members share the contagious mutagens that can be passed by close exposure.

Answers

Answer:

Family members have a similar genetic make-up that may make them predisposed to cancer.

Explanation:

Variation in certain genes can increase the risk of developing certain cancers. This is why certain cancers run in families. There are lots of examples where the risk factor is small, but in some cases, the risk factor is very large.

For example, mutations in BRCA1 are very highly linked to the risk of breast cancer. As a result, many women with mutations in this gene opt to get a mastectomy to reduce their chances of developing breast cancer.

Given that almost all organisms obtain energy from food by the process of cellular respiration, which is the most likely explanation for what prevents Earth from running out of oxygen?

Answers

Answer:

Oxygen cycles keeps the flow of oxygen at a constant rate.

Explanation:

The oxygen constitutes about 20% of the gaseous components in the atmosphere and it's being renewed continuously by the various microorganism and primary producers as green plants that use photosynthesis and converts the sunlight and carbon dioxide to water and releases oxygen. Oxygen cycle makes life possible as most of the elements are combined with oxygen in some way or another and are found on the lithosphere, hydrosphere, and atmosphere even biosphere hence its is present insufficient amounts.

Answer:

A.)     The net effects of the reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle.

but not in animals due to locomotion mode of life

Fungi have cell walls characteristic which fungi share with plants but not animals, hence option C is correct.

What are the characteristics of fungi?

When compared to animals, fungi need prepared organic substances for energy because they are heterotrophic organisms without chloroplasts.

Fungi are eukaryotic organisms, just like plants, and have nuclei in each of their cells. Like plants, fungi lack a cell wall and vacuoles, however, they do have a material called chitin in their cell walls that plants do not. In numerous important respects, fungi are also similar to animals.

Eukaryotic, non-vascular, immobile, heterotrophic creatures are fungi. They could be filamentous or unicellular and spread spores to reproduce. The phenomena of generational alternation are seen in fungi.

Therefore, in comparison to plants, fungi have vacuoles and a cell wall.
