Answers

Answer:

Plants reform the carbon into climatic carbon dioxide into carbon-containing organic compounds, such as sugars, fats, and proteins. Plants take in carbon dioxide by minute openings into their leaves, called stomata. They connect atmospheric carbon with water and produce organic compounds, utilizing energy trapped from sunlight in a method called photosynthesis. The by-product of photosynthesis is oxygen, which plants discharge into the atmosphere by the stomata.

Answer: 1. C) increased water temperature upstream. 2. D) introduce new predators to an environment. brainliest??

Explanation:

The change that is an environmental effect of building dams is increased water temperature upstream, which is in Option C, and humans can increase the rate of endangered or extinct species by reducing environmental impacts, which is in Option A.

What is Human activities on species?

Human activities are the primary cause of species endangerment and extinction, so humans must take actions to reduce environmental impacts in order to increase the rate of endangered or extinct species, and by reducing hunting and poaching and restoring degraded ecosystems can help protect endangered species, and reducing carbon emissions and promoting sustainable development can help mitigate the effects of climate change.

Hence, the effect of building dams is increased water temperature upstream, which is Option C, and humans can increase the rate of endangered or extinct species by reducing environmental impacts, which is Option A.

You have colonies growing on a culture and are going to identify them. First, you do a Gram stain and viewing it on 1000x magnification, you see Gram positive cocci, no predominating arrangement. What test should you do to determine if it a staphylococcus or a streptococcus

Answers

Answer: The test that's should be done to determine if it's a staphylococcus or a streptococcus is a BIOCHEMICAL TEST known as CATALASE TEST.

Explanation:

In the laboratory diagnosis of microbiology samples, GRAM STAINING technique is used to identify bacteria pathogens in specimens and cultures by their gram reactions. The bacteria may be either gram positive or gram negative.

Gram positive bacteria when views with ×100 oil immersion stains dark purple with crystal violet and are not decolorize by acetone or ethanol. Examples of gram positive bacteria include:

--> Staphylococcus

--> Streptococcus

--> Clostridium

--> Corynebacterium

Since a gram positive cocci was identified without a predominating arrangement, further biochemical test known as catalase test should be carried out to determine if the cocci is staphylococcus or a streptococcus.

CATALASE TEST is used to differentiate those bacteria that produce catalase enzyme such as staphylococcus from non- catalase producing bacteria such as streptococcus. Catalase acts as a catalyst in the breakdown of hydrogen peroxide to oxygen and water. An organism is tested for catalase production by bringing it into contact with hydrogen peroxide. Bubbles of oxygen are released if the organism is a catalase producer, therefore staphylococcus but if no bubbles are observed, it's a streptococcus.

The six (6) regions of the  human body from which hair can  be derived are:

1. Head.

2. Eyebrow.

3. Beard.

4. Pubic area.

5. Body.

6. Armpit (underarm).

Hair can be defined as a threadlike, keratinous filament that typically grows out of the epidermis. Also, an epidermis is the outer layer of the skin.

Many of the hardest rocks are metamorphic rocks. Why do you think metamorphic rocks are harder than sedimentary rocks?

Answers

Answer:

Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.  

Because their mineral grains grew together tightly during metamorphism, they're generally strong rocks.

calculate the kinetic energy of a dodgeball that has a mass of 2 kg and velocity of 4 m/s after being thrown

Answers

Answer:

Kinetic energy of dodgeball = 16 kg-m/s

Explanation:

Given:

Mass of dodgeball = 2 kg

Velocity of dodgeball = 4 m/s

Find:

Kinetic energy of dodgeball

Computation:

Kinetic energy = (1/2)(m)(v²)

Kinetic energy of dodgeball = (1/2)(Mass of dodgeball)(Velocity of dodgeball²)

Kinetic energy of dodgeball = (1/2)(2)(4²)

Kinetic energy of dodgeball = (1/2)(2)(16)

Kinetic energy of dodgeball = (32/2)

Kinetic energy of dodgeball = 16 kg-m/s

Purple: FF /White: ff the principles of dominance and segregation to analyze the diagram, alleles would you expect in the F1 plants. Thus, option (a) is correct.

What is segregation?

The Segregation Principle defines how pairs of gene variations are divided into reproductive cells. Gregor Mendel discovered the segregation of gene variants, known as alleles, and their accompanying qualities in 1865. During meiosis, allele pairs (different features of the same gene) are separated so that they can pass to distinct gametes.

The diagram was analyzed using the principles of supremacy and segregation. The principle of the impact in segregation was described as Purple: FF / White: ff. This inheritance pattern is known as partial dominance, which means that neither allele is completely dominant over the other: both genotypes can be seen at the same time.

As a result, the Purple: FF /White: ff the principles of dominance and segregation.
