Answers
The question was incomplete as the diagram was missing, however, the correct diagram is attached with the answer -
Answer:
The correct answer is - scale
Explanation:
The thermometer used to measure temperature by comparison of the object or the parameter of the temperature to measure, with a calibrated pattern that is called scale.
A Thermometer has two scales on both left and right side: degrees Celsius on the left and degrees Fahrenheit on the right.
As given in diagram label with "A'' in a circle on the left side is The degrees of the scale.

Explain the basic steps in the first half of photosynthesis (light-dependent reactions). Describe the movement of electrons and the importance of hydrogen ions in developing a proton gradient that allows for ATP production.
Answers
Answer:
Photosynthesis is the process by which plants make their own food in the presence of sunlight by utilizing carbon-dioxide and water and produces oxygen and energy.
The process of photosynthesis has two types of reactions: light-dependent reactions and light-independent reactions.
The light-dependent reactions occur in the thylakoid membranes of chloroplasts in which plants use light energy to form ATP and the reduced electron carrier NADPH.
In this reaction, photosystem II (P700) absorbs lights energy and passed it to reaction center. this energy is then is transferred to photosystem I (P680), that pump an electron to a high energy level. The high-energy electron then travel to an electron transport chain and releases energy. this released energy pump H+ ions into the thylakoid interior from the stroma and build a gradient H+ ions move through gradient and they pass through ATP synthase resulting in the formation of ATP.
The higher energy electron as moves into an electron transport chain, the electron is passed to NADP+ to form NADPH.
Answer:
In the light-dependent reactions of photosynthesis, electrons become excited after photons strike the light-absorbing pigment chlorophyll. These excited electrons are then transferred from the chlorophyll to the electron transport chain. To replace the loss of electrons from the chlorophyll, water molecules present in chloroplasts are split in a process called photolysis. The separate components of water get recycled and used. The freed electrons replace those that supported the electron transport chain. The released hydrogen helps to develop a proton gradient in the thylakoid membranes. This gradient helps to fuel the production of ATP.

What happens to the molecules of a substance when heat is added to it ?
Answers
Answer:
The molecules start to energize.
Explanation:
When you heat up any molecule, the atoms and molecules start to vibrate more energetically. When this happens, it increases the space in-between the atoms. The substance expands and takes up more space as atoms move faster and farther away.

A nonnative species of beetle is introduced into a woodland ecosystem.
Which of the following would be most likely to stop the species from
becoming invasive?
O A. There are no other beetle species living in the woodland
ecosystem.
B. Native beetle species outcompete the nonnative species.
C. The nonnative species has no predators in the woodland
ecosystem
D. The nonnative species tolerates the woodland's abiotic factors.
Answers
Answer:
B. Native beetle species outcompete the nonnative species.
Explanation:
If native species outdoes the nonnative then the nonnative species cannot become invasive and take over the ecosystem.
Native beetle species outcompete the nonnative species would be most likely to stop the species from becoming invasive. So, the correct option is B.
What is Invasive species?An invasive species is defined as an organism that is not indigenous or native to a particular area, which can cause enormous economic and environmental damage to the new area. Not all non-native species are invasive species.
Non-native species affect an ecosystem because they are organisms that are living outside their natural range which is like pollution and can harm or destroy the native species as they depend on them for their food and water. Native species outcompete the nonnative species would be most likely to stop the species from becoming invasive
Therefore, the correct option is B.

A population of 40 killer whales lives in a bay that measures 2000 square miles. What is the population density of killer whales?
Answers
Answer:
.02
Explanation:
When finding population density, divide the amount of people, animals or things in the region by the total square miles. 40/2000 is .02.
A population is the size of the group of individuals residing at a place. A population of 40 killer whales has a population density of 0.02.
What is population density?Population density is the individual's concentration of a specific species at a particular geographical location. It allows the establishment of the ecosystem and health.
Given,
Number of individulas = 40
Size of the area = 2000
Density = Number of individuals ÷ Size of the area
= 40 ÷ 2000
= 0.02
Therefore, 0.02 is the population density of killer whales.

A mutation in which the gene that altered carries out the production of the product that has a new pattern of gene expression or a new molecular function.
Function mutations are always gain by almost always Dominant or in some rare cases semi-dominant so, the mutation in a coat color gene of a mouse alters an enzyme such that it produces a red pigment instead of the wild type, which is tan. This is a gain of function mutation, which is most likely dominant.
