Answer:
Elements that are found in the same horizontal row (belong to the same period) in the periodic table, e.g. Fluorine and Neon both have the same energy level of 2.
Note: The question does not specify any two elements.
Explanation:
The modern periodic table is organized into eight vertical columns known as groups and seven horizontal rows known as periods. The atomic number ( number of protons in the nucleus) of elements increases when moving across the periodic table from left to right. The horizontal rows or periods represents an energy levels or the number of electron shells in an element. Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Elements belonging to the same period have the same number of energy level or shells. For example, the elements belonging to Period 2 include lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. These all have the same number of energy level of 2.
The graph below shows the energy associated with a chemical reaction. The activation energy decreases once a certain type al molecule is added
What type of molecule causes the activation energy to decrease as shown in the graph?
Liquid
protein
nucleic acid
carbohydrate
Answer:
C.
Explanation:
I'm doing it now
The type of molecule that causes the activation energy to decrease is a PROTEIN.
Proteins are biomolecules composed of amino acids linked via peptide bonds.There are two major classes of proteins: structural proteins and enzymatic proteins.Enzymatic proteins catalyze specific chemical reactions by lowering the activation energy.In conclusion, the type of molecule that causes the activation energy to decrease is a PROTEIN.

One oak tree cell with 14 chromosomes undergoes meiosis. How many cells will result from this process,???
Answer:
Four (4) cells
Explanation:
Meiosis is the type of cell division in which four daughter cells that are genetically different is produced. The daughter cells are gametes that have undergone a reduction in their chromosome number (by half).
For example, one cell of an oak tree with 14 chromosomes is said to undergo meiosis. This means that, based on the explanation of meiosis above, the oak cell will give rise to four (4) daughter cells containing 7 chromosomes each.
The process of counting a portion of a population of a species in a particular area and using that number to estimate
the total population without physically interacting with the species is called
A restoration
B) mark/recapure
C) bottlenecking
D) sampling
E) arcology
Answer:
I think it's sampling, since mark/recapture involves scientists to have to interact with the animals.
Explanation:
The process of counting a portion of a population of a species in a particular area and using that number to estimate the total population without physically interacting with the species is called sampling. Thus, option D is correct.
What is sampling?Sampling is the process of choosing a portion of a statistical population to estimate attributes of the entire population in statistics, quality control, and survey methods.
Statisticians try to get samples that are typical of the population under consideration. Using samples, one can draw conclusions about populations. Since samples are useful, affordable, practical, and manageable, it is simpler to gather data from them.
Therefore, option D is correct, that sampling is the method of counting a portion of a species' population in a certain location and using that figure to calculate the total population without actually interacting with the species.

Selective breeding______.
Answer:
#2
Explanation:
Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
Which is correct if it is not correct, correct it.
Simple or facilitated diffusion requires cellular energy.
Diffusion results in a net flow of solute down a concentration gradient, while active transport works against the concentration gradient.
Secondary active transport uses energy to set up a concentration gradient which then allows some passive diffusion to occur, recapturing some of the energy expended.
Membrane proteins are required for all membrane transport into and out of cells.

How can natural selection lead to change in allele frequency
Answer:
Natural selection can cause microevolution, or a change in allele frequencies over time, with fitness-increasing alleles becoming more common in the population over generations. ...

What are some "topics" to be considered when discussing the California Current
Ecosystem
Answer: Red tide events
Explanation:
Red tide events causing massive fish die-offs, unprecedented sea ice loss, erosion of coastal wetlands, and bleaching of coral reefs not only impact marine ecosystems but also communities, peoples' well-being, local businesses, and more.
These issues impacting ecosystems and people require solutions that consider ecosystems and people. These types of solutions are Ecosystem-Based Management, which considers social, economic, and ecological trade-offs when deciding how to address these issues.

why does the illumination of the moons surface appear to change when viewed from earth even through the sun continuously illuminates half of the moon?
Answer:The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. This is caused by the different angles from which we see the bright part of the Moon's surface. These are called "phases" of the Moon.
Explanation:
A student performs an investigation
to determine if keeping plants in a
greenhouse will reduce the amount
of water lost to evaporation. The
student hypothesizes that if a plant
is in a closed, humid environment,
then less water will be lost to
evaporation. The student places the
plants in beakers of water and then
sets some beakers inside and some
beakers outside of a greenhouse,
She then measures the amount of
water lost from each beaker, Which
table should the student use to
collect the data needed to test her
hypothesis?
Answer:
C
Explanation:
Measure the volume of the water of the plants in and outside. Then note how many days have passed
Table C should be used to collect the data needed to test her hypothesis. Every time the temperature rises, so does the rate of evaporation.
What is evaporation?Water moves from either a liquid form to something like a gaseous state through evaporation. Water boils at a temperature of 100 degrees Celsius, yet it evaporates relatively slowly at 0 degrees. Every time the temperature rises, so does the rate of evaporation.
Depending on the temperature and the quantity of water that has to evaporate, water evaporates at different speeds. Take a desert, for instance, and consider how little evaporation occurs there despite it being quite hot. Table C should be used to collect the data needed to test her hypothesis. When a liquid changes from a liquid to a gas, evaporation occurs. The reaction starts when the liquid's molecules receive energy in the shape of heat.
Therefore, the correct option is option C.

Which chemical weathering processes rely primarily on water? Select the two correct
answers
oxidation
hydrolysis
dissolution
precipitation
Answer:
hydrolysis and dissolution
Chemical weathering frequently involves the presence of water, whether it is in liquid or solid form, hence options B and C are correct.
What is chemical weathering?For instance, water in liquid form can seep into the fissures and cracks of the rock. The water will freeze if the temperature falls far enough, water expands as it freezes. Hydrolysis is a well-known kind of chemical weathering.
Chemical weathering is an erosive process in which chemical processes break down rocks and other materials (predominantly by water and chemicals dissolved within it).
When water comes into touch with rocks, the minerals that make up those rocks break down into individual components.
Therefore, as compounds in rock interact with water during hydrolysis, a new solution (a combination of two or more substances) is created, hence options B and C are correct.

Viewing eubacteria requires a microscope,because they all single celled organisms.another word for single celled is_______
Answer:
The correct answer is - prokaryotic and unicellular.
Explanation:
Eubacteria is known as the true bacteria and belongs to the prokaryotic type of cells which is characterized by no double-membrane organelles or the nucleus. All the genetic material is present in the cytoplasm itself.
These bacteria are single-cell microscopic organisms as they are very minute to see by the naked eyes and required a microscope to study. Another word for the single-cell organisms is unicellular.
