sixth mass extinction.
What evidence do we have that we are losing species at more than the normal rate?
Answer:
Most ecologists believe that we are in the midst of the sixth mass extinction. Humanity’s impact on nature, they say, is now comparable to the five previous catastrophic events over the past 600 million years, during which up to 95 percent of the planet’s species disappeared. We may very well be. But recent studies have cited extinction rates that are extremely fuzzy and vary wildly.

Are there ways that reef might provide benefits to people on land, not just marine life?
Answer:
Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines.
Over half a billion people depend on reefs for food, income, and protection. Fishing, diving, and snorkeling on and near reefs add hundreds of millions of dollars to local businesses. The net economic value of the world’s coral reefs is estimated to be nearly tens of billions off site link of U.S. dollars per year. These ecosystems are culturally important to indigenous people around the world.

Joanna read that certain perfumes would cause bees to leave the hive and act in an agitated fashion. She decided to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Mark Jacobs, Vera Wang, and the last is an odorless liquid. She placed a saucer containing 20ml of perfume A 10 meters from a beehive. She then recorded the total number of bees that emerged from the hive during a 15 minute interval and made observations on their behavior. Using a 30 minute interval between tests to allow recovery time for the bees, she then repeated the procedure to test the remaining three samples. Each test was conducted on the same day with similar weather conditions. whats the independent variable
Answer:
PERFUME
Explanation:
In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter in order to effect a measurable response in the dependent variable.
In this experiment, Johanna is trying to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Mark Jacobs, Vera Wang, and an odorless liquid, which is the control. Hence, the PERFUME is the independent variable because it is the manipulated variable.
how do mountains influence climate?
Answer:
Explanation:
They affect climate by blocking wind and receiving more rainfall than low-lying areas. As air is forced over higher ground, it cools, causing moisture to condense and fall as rain. The higher a location is above sea level, the colder it is.
Answer:
Mountains can affect the climate of nearby lands. In some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. Much of airborne moisture falls as rain on the windward side of mountains.

What is the difference between the DNA of a dog and the DNA of a fly?
A. The strength of covalent bonds.
B. The sequence of nucleotides.
C. The strength of hydrogen bonds.
D. The type of sugar building blocks.
Answer:
B. The sequence of nucleotides.
Explanation:
Different proteins build up.
The difference between the DNA of a dog and the DNA of a fly is the sequence of nucleotides (Option B). All organisms have DNA in their cells.
Desoxyribonucleic acid (DNA) is a molecule that contains the instructions (i.e., the genetic material) required to build and maintain the homeostasis, i.e., the internal equilibrium, of an organism.
Structurally, this molecule (DNA) is the same in all organisms.
DNA is composed of two long chains of nucleotides linked together by hydrogen bonds. The linear order of these nucleotides (i.e., Adenine, Guanine, Cytosine, and Thymine) determines the type and amount of proteins that are synthesized from a genome.
In conclusion, the difference between the DNA of a dog and the DNA of a fly is the sequence of nucleotides (Option B).

After a protein is made in the endoplasmic reticulum of an animal cell, it A) attaches to a ribosome on the ER membrane to be encoded and used in DNA replication B) is sent to the Golgi apparatus to be processed, stored, and sent to another destination C) is stored in the large central vacuole until it is needed by the cell for growth and repair D) travels to the mitochondria to be broken down and used for energy to power the cell
Answer:
B) is sent to the Golgi apparatus to be processed, stored, and sent to another destination
Explanation:
Proteins are important biomolecules produced in the cells of living organisms, specifically the Rough Endoplasmic reticulum (RER) attached to the ribosome (site of protein synthesis).
However, after production by the RER, the protein is sent to an organelle called the Golgi apparatus in order to be processed, stored, and sent to another destination by transport vesicles.

Answer:
Microorganisms that are not visible are so called because their measurements are in micrometers and even nanometers.
We usually talk about viruses, bacteria, fungi and even parasites.
Explanation:
Microorganisms are mostly pathogens for humans, but others make up the commensal biota of the same living being.
Not all microorganisms need the same means to live and develop as large organisms such as those that are simple to the human eye.
Some microorganisms are seen by optical microooscopy and others smaller by electronically.

what role did gravity play in the formation of the sun
Answer:
Gravity played a lot of roles in the formation of the sun and solar system. Gravity drew dust and gas together to create the young solar system. The sun formed first from the vast material, gravity caused the solar nebula to collapse toward the center. Which is what caused the hot core of the sun.
Simple terms, gravity helped push dust gases called the nebula which later formed the sun with a couple other things that played a role with the formation.
Explanation:
Hope this helps! <3

A common test for liver function involves sprinkling sulfur powder onto a sample of urine (mostly water with dissolved bodily waste). Sulfur powder sprinkled on a sample from an Individual with impaired liver function will sink because the urine contains a high level of bile salts, while the sulfur powder sprinkled on normal urine samples will float.
Bile salts decrease the surface tension of the urine sample, that’s why the sulfur will sink in a sample from an individual with impaired liver function since it contains high levels of bile salts.
Bile salts caused the sulfur powder to sink because bile salts decrease the surface tension of the urine sample.
Liver function test are test procedures that are used to diagnose and monitor liver disease or damage.
When the liver is malfunctioning, such as in cases of hepatitis and cirrhosis, high level of bile salts are present in the urine. This is as a result of high serum bilirubin.
One of the fastest methods to carry out a test for liver function is sprinkling sulfur powder onto a sample of urine.
Surface tension is the quality displayed by water that enables substances of greater density float on it.
The bile salts is able to decrease the surface tension of the urine sample causing the sulfur powder to sink.
