Answers

Answer:

Soil and gases or particles in air

Explanation:

The solid part of Earth is called its geosphere. The geosphere includes the rocks, minerals, and landforms of the surface and interior of our planet.

The atmosphere of Earth is the layer of gases that surrounds it. This layer of gases is what we call the air.

Based on this information, we can conclude that all interactions between the atmosphere and geosphere include the soil and gases or particles in the air.

How can both of these samples be pure phosphorus?
State your claim. Make sure your claim fully explains how the two samples can both be pure phosphorus. Summarize the evidence you have gathered to support your claim and explain your reasoning.

Answers

Answer:

If impurities are removed from the samples, pure phosphorus will be obtained.

Explanation:

Both of these samples be pure phosphorus if the atoms and other impurities are removed from chemical as well as physical means. Pure phosphorus means that there is only atoms of phosphorus present but pure phosphorus is not available because of its reactivity so for that reason it reacted with the oxygen present in the air and formed phosphate molecules and stabilize itself.

which of the following would likely NOT increase a reaction rate of an enzyme in your mouth that was not yet at optimal conditions?
1)slight increase in temperature
2) neutral ph
3) more enzyme
4) more substrate
5) extremely high temperature

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.

Which part of photosynthesis is represented by the diagram to the right

Answers

Answer:

Light-dependent reactions

Explanation:

Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.

The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).

A group of students wanted to know if millipedes prefer moist or dry environments. They suspected that millipedes would prefer moist environments because they had observed that millipedes are usually found under decaying logs.

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.

Birds belong to different species but share similar characteristics. What inference can be correctly drawn about this statement? (5 points)


Group of answer choices


All birds share the same habitat.


All birds produced similar offspring.


All birds reproduce with genetic variation.


All bird species adapt through evolution

Answers

Answer:

All bird species adapt through evolution

Explanation:

The correct answer would be that all birds reproduce with genetic variation and adapt through evolution.

Sexual reproduction causes genetic variation in sexually reproducing organisms due to crossing over and a random assortment of genes. Birds can only reproduce sexually and hence. they produce offspring that are genetically different but that might share many similar characteristics.

Evolution refers to the development of complex organisms from simple ancestral ones. Organisms change and evolve as they constantly try to adapt to their changing environments. Hence, organisms of the same species growing in a different environment might end up becoming different species as a result of adapting to their different environments, although they would still have some similarities to one another. In other words, evolution has a tendency to cause speciation.

Use an example from nature to explain how natural selection causes populations to change as their environment change include the following terms variation trait genes

Answers

Answer:

Galapagos finches have various beak sizes that make foraging for food more successful.

Explanation:

Organisms evolve over time due to changes in their genome. These are pontaneous, and occur in DNA at random. These changes are called mutations and form alleles or different forms of a gene.

Over time within a population, the number alleles increase the variation of the population. These variants may confer specific traits within an individual, that may confer a biological advantage.

Thus, the trait may make the organisms more capable of obtaining food, shelter a mate etc. or ensure survival, i.e. they are able to pass on their genes to the next generation.

In your Punnett Square activity, you chose beads which represented
genes and used Punnett Squares to determine possible offspring. If
your first parent genotype was yellow bead and blue bead and the
second parent genotype was blue bead and blue bead, how many
offspring out of 4 have the yellow kernel phenotype?
please please!!

Answers

Answer:

Two out of four offsprings have the yellow kernel phenotype.

Explanation:

The information that we have is that one parent's genotype is yellow bead (Y) and blue bead (B), and the other parent's genotype is blue bead (B) and blue bead (B).

Parent 1: YB

parent2: BB

If we make a Punnett Square, we can see that two out of four offspring will have the yellow phenotype.

  ║ B   ║ B   ║

Y║ YB ║ YB ║

B ║ BB  ║ BB ║

The offspring out of 4 have the yellow kernel phenotype in the given case would be - two or 50%

We are given that the kernel color is represented by two beads, yellow and blue beads.

Let us consider yellow bead be represented as Y and blue bead be represented as y. Yellow color is dominant over blue kernel color.parent 1 has a genotype of a yellow bead and a blue bead represented as Yy.parent 2 has a genotype of the blue bead and blue bead, i.e, yy.

The cross can be given as,

Genotype Y y

y   Yy     yy

y    Yy     yy

Now, two of the four offspring have Yy genotypes.

Thus, 2/4 or 50% of the offspring have a yellow kernel phenotype.

Answers

It’s number 4,fluid(flexible)!!

Answer:

4. Fluid (Flexible)

Explanation:

Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.

Stagnant, shallow areas of water-saturated soil, where the rate of photosynthesis is low, are best characterized as:______.
