List 3 negative impacts does plastic pollution have on the ocean?
Answers
Ingestion
And suffocation
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

Summarize: How are respiration and photosynthesis related to each other? ___________________________________________________________________________________________________________________________________________________________________________
Answers
Answer: Plants gain energy in photosynthesis from sunlight while in respiration, the breakdown of glucose molecules takes place to get energy in the form of ATP molecules. Also, When Plant release Oxygen humans and other species that need oxygen take it in and use it for respiration, and when species that go through respiration like humans do we release Carbon Dioxide for plants to use during photosynthesis
Explanation:
Answer:
Photosynthesis and respiration are linked through the exchange of energy and matter. Photosynthesis captures energy from sunlight and converts it into chemical energy that can be stored in organic molecules, while respiration converts this stored chemical energy into a form that can be used by living organisms.
Explanation:
Photosynthesis is the process by which plants, algae, and some bacteria convert energy from sunlight into chemical energy, which is stored in the form of glucose and oxygen. This process occurs in the chloroplasts of plant cells and is powered by the energy from sunlight, which is absorbed by pigments such as chlorophyll.
Respiration is the process by which living organisms, including plants and animals, convert chemical energy stored in organic molecules into energy that can be used to power their biological processes. This process occurs in the mitochondria of cells, where glucose and other organic molecules are broken down to release the energy stored in their chemical bonds. The energy released during respiration is used to produce ATP, a molecule that stores chemical energy.

Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

This is an illustration of a typical food web. You might see a food web like this where you live. The organisms responsible for changing sunlight into food would be the Response area. Grass is one of these. You can see that the grasshopper and rabbit eat the grass and the bird and the shrew eat the grasshopper. Imagine that there was a big increase in the number of snakes in this area. We would then expect the Response area numbers to drop. In this food web, we consider the hawk a Response area. If the hawk population increases, we would see a drop in birds and shrews and snakes! The fungi and bacteria in the food web are examples of Response area. They break down any and all dead organisms. This helps to recycle matter.

Answers
Answer:
A. Examples of laboratory hazards:
In general, there are three types of hazards personnel may encounter while working in laboratories at the NIH.
Possible hazards include:
• Biological Hazards – bloodborne pathogens
• Chemical Hazards – carcinogenic, flammable, or corrosive materials
• Physical Hazards – pyrophoric materials, lasers or radiation.
It is possible, even common, for a single laboratory to have types of hazards associated with more than one of
these categories at once. Engineering controls should be used as primary barriers, functioning to contain the
hazards. Personal protective equipment (PPE) should be used in combination with engineering controls to
reduce the risk of worker exposure to laboratory hazards. A risk assessment should be used to determine the
hazards associated with a particular laboratory or laboratory operation, and establishing which engineering
controls should be utilized and what PPE should be selected. Information on how to perform a risk assessment
is described in Biosafety in Microbiological and Biomedical Laboratories 5th Edition. For assistance with
performing a risk assessment and selecting proper PPE, please contact your Institute's Safety and Health
Specialist, or the Division of Occupational Health and Safety.
B. Appropriate laboratory attire, laboratory coats and applicable standards:
While in a laboratory at the NIH for any reason, all personnel must wear appropriate clothing attire that prevents
direct contact of materials with the skin. Examples of attire that is appropriate includes long pants or leg
coverings and closed toe shoes. In addition, a task appropriate laboratory coat, as determined by a risk
assessment, must be worn while performing laboratory operations. Following a thorough risk assessment,
guidance to the selection of laboratory coats can be obtained from Tables 1 and 2. Table 1 lists the three types
of laboratory hazards and the applicable laboratory coat material standards. Table 2 provides a more detailed
description on the application of these standards and examples of laboratory coats that meet these standards.
Table 1. Summary of laboratory hazards and applicable test standards
Type of Laboratory Hazard Applicable Test standard
Biological Hazards ASTM F1670 (penetration by synthetic blood) and
ASTM F1671 (bloodborne pathogen exposure)
Liquid or Chemical Hazards AATCC Method 42 (resistance to the penetration of
water by impact) and ASTM F903 (liquid chemical
barrier)
Physical Hazards NFPA 701 or 2112 (flame propagation tests)
The standards listed in Table 2 serve as standardized testing methods to determine protection levels of materials
against certain hazardous or hazard surrogates. These standards should be considered when selecting a
laboratory coat material when working with the hazards that correspond to the applicable hazard or hazard
surrogate tested. These testing methods only test the material and do not test the complete laboratory coat
making it important to consider characteristics of the laboratory coat such as seams, stitches and where the
openings, snaps or buttons are located when selecting a laboratory coat. A complete description of the
standards can be viewed by contacting your Institute's Safety and Health Specialist,

In the same science fair, Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscope, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm.
List three controlled variables in this experiment.
Answers
Answer:
Independent variable- effect of caffeine
Dependent variable- heart rate
Hypothesis- If a stimulant such as caffeine is administered to earthworm, then its heart rate increases. The experiment is based on the research question; "Does caffeine increase the heart rate of an earthworm?" We can see from this research question that the independent variable is the effect of caffeine and the response it produces is a change in the heart rate (the dependent variable)
This now leads us to a hypothesis that states thus; 'If a stimulant such as caffeine is administered to earthworm, then its heart rate increases.'
Controlled variables are:- amount of caffeine she adds
- earth worm (in natural state)
- how much caffeine is actually absorbed by the worm
Answer:
Controlled variables are:
- amount of caffeine she adds
