Explanation:

In general, photosynthesis in cyanobacteria uses water as an electron donor and produces oxygen as a byproduct, though some may also use hydrogen sulfide a process which occurs among other photosynthetic bacteria such as the purple sulfur bacteria. Carbon dioxide is reduced to form carbohydrates via the Calvin cycle.

The solid piece of ice would break more easily than that of the solid piece of copper metal because ice can be broken more easily than copper metal. The affinity is stronger in metals than water.

Pure substances can be defined as the substances which are made up of only one type of atom or only one type of molecule such as water. All the constituent particles of a substance are the same in their chemical nature and physical properties. For example, the elements and compounds.

Matter is a substance which can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds which are similar. A chemical substance is composed of only one type of atom or molecule. However, a mixture is composed of different types of atoms or molecules which are not chemically bonded to each other. The chemical bonds are stronger in copper metal than that of ice. That's why, it is easier to break apart ice than copper metal.

Answer:

Firstly, Milk alone did not ferment or change in pH at all, showing that it is a control variable on this experiment. The L. bulgaricus culture alone did not meet Madison's goal to make yogurt with a pH of 4.5 within 4 hours; however, the mixed culture S. thermophilis and L. bulgaricus met Madison's goal of reaching a 4.5 pH. In conclusion, the mixed culture is the fastest fermenting culture that madison has, and it meets her goal of reaching a pH of 4.5 in the optimal time of 4 hours.

The total amount of organic matter from plants and animals in a habitat.

Explanation:

Biomass can be defined in ecological terms and in industrial (environmental science) terms. Ecologically, it is defined by the total mass of organisms (not organic matter) given a specific area or ecosystem. This definition is not in the choices therefore the industrial term for environmental science should be appropriate. In environmental science, biomass is the organic matter from living organisms whether wastes or dead animals or plants that can be used as fuel in powering power plants to produce electricity (mainly). Therefore from that definition, the correct answer is: All materials that form from the remains of living organisms.

Answer:

C. 24

Explanation:

The correct option is (B). 24.

A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.

Moreover, chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

Therefore, chromosomes are threadlike structures made of protein and a single molecule of DNA that serve to carry the genomic information from cell to cell. In plants and animals (including humans), chromosomes reside in the nucleus of cell.

Answer:

B

Explanation:

When the air temperature is equal to the dew point temperature, the relative humidity would be 100% and condensation occurs.

The dew point temperature is a temperature at which the air is saturated with water vapor and some of it begins to condense as liquid water. As the air temperature cools further, more and more water condenses as liquid water and this is essentially what constitutes precipitation.

The correct option is B.

Answer:

The five spheres of Earth are the geosphere, hydrosphere, atmosphere, cryosphere, biospheres.

The ocean is one environment that is comprised of both the hydrosphere and biosphere. The ocean, being nothing but water, serves as the whole known world to all marine life within, which serves as the biosphere component.

Mountainous environments are also made up of multiple spheres; including, but not limited to, cryosphere, geosphere, with a little bit of biosphere as well. Mountains--which are giant rock formations created by years of seismic activity--are mostly covered in snow near the peaks due to low temperature, which will melt at different points during the year. A small assortment of wildlife call these areas home, such as jackrabbits, white-tailed deer, mountain goat, bear, gray wolf, coyote, lynx, and wolverine.

Answer:

Independent variable: The fertilizer given

Dependent variable: Daily plant growth

Constants: How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)

Explanation:

Independent variable of an experiment is the variable that is changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment where Sherri wanted to test what fertilizer worked best on her tomato plants. She used 4 different brands of fertilizer. Hence, the FERTILIZER is the independent variable

On the other hand, the dependent variable is the variable that is measured in the experiment. It is the variable that responds to the independent variable. In this experiment, the DAILY PLANT GROWTH is the dependent variable.

Constants are variables that are kept unchanged or constant throughout the experiment. In this case, the constants or controlled variables are: : How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)
