A. If 15 ml of a liquid has a mass of 11.85 grams,
(1) What is the density?
(2) What is the liquid?
Answer:
1. 0.79g/mL
2. Ethanol
Explanation:
The density of a substance can be calculated by using the formula;
Density (g/mL) = mass (g) ÷ volume (mL)
According to the information provided in the question, mass = 11.85grams, volume = 15mL.
Hence, density = 11.85g ÷ 15mL
= 0.79
Density of the liquid = 0.79g/mL.
Substances usually have their own unique density, which is one of the properties that distinguish them. In this case, ETHANOL is the liquid that possesses a density of 0.79g/mL.
Which of the following correctly explains the differences between artificial and natural selection?
Not sure what the options are, but artificial selection would be when farmers/breeders choose only to plant/breed the organism with desired characteristics in order to cause the evolution of the trait while natural selection is when organisms that are better adapted to their environment usually survive and produce offspring, causing the evolution of their traits which help them to survive.

what type of pollination happens when pollen grains from anther are transferred to the stigma of a flower what belongs to the same plant?
A.across-pollination
B.auto-pollination
C.cross-pollination
D.self-pollination
Answer:
It is D
Explanation:
Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Which are ways that humans can lower biodiversity as they us environment? Check all that apply. A. Converting a forest to soccer fields B. Spraying pesticides on lawns An C. Building roads across tundra D. Replacing riverbanks with concrete bulkheads and
Answer:
A, B, C, and D
Explanation:
All of the options represent ways by which humans can lower biodiversity as they use the environment.
By definition, biodiversity or biological diversity of an area refers to the total number of living organisms that are domicile in that area.
Converting a forest to a soccer field requires that the variety of plants and animals in the forest are removed and the forest soil is planted with turfs in their place. Thus the biodiversity of the forest has been greatly reduced in other to pave way for a soccer field.
A pesticide is an agrochemical that kills pests. Pests are biological organisms even if they are not that desirable on the lawn. Thus, killing them off using a pesticide is a way of reducing the biodiversity associated with the lawn.
A tundra represents an ecoregion with its own characteristic plants and animal, even if they are few. Hence, building roads across tundra requires that portions of the biodiversity are removed to pave way for the road.
Riverbanks serve as habitats for a variety of living organisms. Replacing them with concrete bulkheads means that the habitat is lost and the organisms displaced. Thus, the biodiversity of the region gets reduced.
Therefore, options A, B, C, and D are all correct.

why is there a crisis if "energy can neither be created or destroyed"?
Answer: Scientists say that energy can neither be created nor destroyed, so therefore it is impossible for there to be an energy crisis.
Explanation:
I'm pretty sure I'm right
Answer:
There is a problem because if energy is created as machines worked everything would speed up until it breaks, and if energy was destroyed as machines worked everything would eventually slow down and stop. So in both cases the world would end, a whimper in one a bang in the other.
Explanation:
Reference: How things Work Now(book)
name an organelle that can be found in a bacterium
Answer:
lysosomes
Explanation:
1. Explain how the atomic number and mass number of an atom can be used to determine the number of
electrons and of neutrons respectively.
Because the total of neutron and proton/electron is the atomic mass. So if you wanna find proton/electron and you know the neutron, just minus the atomic number with the neutrom and you will get the proton
Here if you need the formula
Atomic number = Total neutron + Total proton or electron
7. Explain how the equations for photosynthesis and cellular respiration compare.
Answer: In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water. C6H12O6 (glucose) + O2(oxygen) → CO2(Carbon Dioxide) + H2O(water) + ATP energy. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

explain thourough what pollution is
Answer: Definition and models Contamination alludes to the presence of a substance or substances in the climate that is unsafe or harmful. The substances or poisons might be hurtful to human wellbeing, different creatures, and plants. When something hurtful enters the climate at a quicker rate than it tends to be scattered, there is contamination. or Contamination is that the presentation of hurtful materials into the climate. These unsafe materials are called toxins. Poisons might be normal, as volcanic debris. they'll even be made by human activity, similar to waste or overflow created by industrial facilities. Contaminations harm the norm of air, water, and land. Explanation: Both describe what pollution means I hope this helps you
Which of the following is NOT an ecosystem
service that forests provide?
habitat for wildlife
reduce soil erosion
lumber
carbon sink
all of the choices are ecosystem services
Answer:
All of the choices are ecosystem services.
Explanation:
Trees' roots hold soil down so it doesn't move everywhere and they recycle carbon into oxygen. In addition, they provide us wood and beautiful wildlife!
Have a great day!
The ecosystem services are all the benefits provided by the ecosystem to human. Otion A) habitat for wildlife is not an ecosystem service.
What are the Ecosystem Services?
When talking about ecosystem services, we are referring to the goods and services offered by ecosystems to human populations
There are different types of ecosystemic services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing.
Among them, we can mention food, clear fresh-water, fertile soils, geotic materials, raw materials (used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, and others.
Regulation:Refers to ecological processes that improve life.
Among others, we might mention climate regulation, CO₂ absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil formation and fertility maintenance, nutrient cycling, waste recycling, pests/plagues control, etc.
Cultural:Refers to the benefits that are not material.
Ecosystems also provide a recreational place or area to spend time, learn. They are a spiritual/religious space, a source of inspiration. They are considered to be cultural patrimony and the source of scientific knowledge.
Among th options, the one that is not a ecosystemic service is option A) habitat for

What is the relationship between the levels of CO2 in the atmosphere and the levels of CO2 in the ocean?
Answer:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

brief explain the roles of the following in photosynthesis 1 NADP 2) Ribubose diphostate 3) photosytem 1 ad 2
Answer:
1) NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.
3) Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems: photosystem I (PSI) and photosystem II
● PhotosystemSII acts first during the light transformation process in photosynthesis.
● Photosystem1 is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from
plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by carrier NADPH.
