Which is a characteristic of diatoms?
Diatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric.
What are Diatoms?Any member of the vast group of several genera of microalgae that can be found in the world's oceans, streams, and soils is referred to as a diatom.
Diatoms can photosynthesize, which allows them to change the dissolved carbon dioxide in the water into oxygen.
For higher-ranking organisms in the food chain, like invertebrates and tiny fish, they serve as a major source of food. In the energy and nutrition cycles of water resources, diatoms can also be vital players.
Diatoms can be divided into two shapes: pennate diatoms, which make up the majority, are broadly bilaterally symmetric, and central diatoms, which make up the minority.
Thus, these are the characteristics of diatoms.

Explanation:
explain the flow of energy of candles
Answer:
The wax vapor catches light and burns, sending a flame high above the wick. Heat from the flame travels in three directions at once by processes called conduction, convection, and radiation. Convection draws hot wax vapors out from the wick and sucks oxygen from the surrounding air into the base of the flame.
Explanation:
Answer:
The heat from the wick melts the wax which gets absorbed in the wick and then gets burnt (which is really oxidation) to produce heat energy as well as light energy. The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light.

18. How has the use of herbicides affected agricultural productivity?
O A. Fewer crops are organic because of the use of Bt toxin.
B. Fewer pesticides are needed because of parasitoids.
O C. Fewer people are needed to weed because of herbicides.
D. Fewer crops are produced because of herbicides.
Answer:
B. Fewer pesticides are needed because of parasitoids.
Explanation:
Herbicides are chemicals utilized to manage or command unwanted vegetation. Herbicide employment happens most commonly in row-crop cultivation, where they are employed before or throughout seeding to maximize yield productivity by decreasing other vegetation. Yields have improved considerably, and, in association with tillage, herbicide use decreases erosion, fuel usage, greenhouse gas discharges, and nutrient run-off, and preserves water.

Phil observes that when he turns on a flashlight, chemical energy from the batteries is transformed into light energy. Phil tries to think of some other ways energy is transformed. Which of the following scenarios describe an energy transformation? Choose the three scenarios that apply.
A. a lamp being turned on
B. a toaster being used to toast bread
C. chocolate melting in your hand
D. a car horn honking
Answer:
A. a lamp being turned on
B. a toaster being used to toast bread
D. a car horn honking
Explanation:
Energy transformation is the conversion of one form of energy to another form in accordance with the law of conservation of energy. According to this question, Phil is observing a flashlight, which turns chemical energy (batteries) into light energy.
From the examples given in this question, the following are examples of scenarios that involve energy transformation:
- A lamp being turned on: This converts chemical energy to light energy.
- A toaster being used to toast bread: This converts electrical energy to heat energy.
- A car horn honking: This converts electrical energy to sound energy.
Note that, melting of a chocolate does not transform any form of energy.

Which component is found in nonvascular plants?
Leaves
Stems
Chlorophyll
Roots
Answer:
Chlorophyll
Explanation:
because they lack roots, stems, and leaves.
The component that can be found in non-vascular plants is chlorophyll. The correct option is C.
What is chlorophyll?Chlorophyll is a pigment that gives plants their distinctive green colour and aids in photosynthesis, which enables plants to produce their own food.
Plants (including algae) can photosynthesize, or use sunshine to change simple molecules into organic compounds.
Chlorophyll makes this possible. The most common kind of chlorophyll found in algae and green plants is chlorophyll a.
Plants lacking a circulatory system made up of xylem and phloem are referred to as non-vascular plants. They may instead have more basic tissues with tailored capabilities for the internal transfer of water.
Mosses, hornworts, and liverworts are examples of nonvascular plants. They don't have leaves, stems, or roots.
Nonvascular plants require a damp environment, are low-growing, and reproduce using spores.
Thus, the correct option is C.

Why is the nucleus called the "control center" of the cell?
Volcanoes can form near coastal regions where an oceanic plate [blank] below a continental plate
Answer:
Subducts
Explanation:
According to Merriam Webster and TheFreeDictionary, the definition of subduct is "A geologic process in which one edge of one crustal plate is forced below the edge of another." Since this sentence indicates that an oceanic plate sinks under the continental plate, therefore I believe the fill-in-the-blank word would be 'subducts' or a similar word.

Cells are open systems that exchange matter and energy with their surroundings. Which of the following best explains
why plant cells require sunlight to make organic compounds, according to Gibbs's theory of free energy?
O The photosynthetic reaction releases free energy to the surroundings.
O The photosynthetic reaction's free energy is in equilibrium.
The reactants of photosynthesis have less free energy than the products,
The change in free energy (AG) of the photosynthetic system is less than zero.
Answer:
I'm not sure if this is correct but I think it's C
Answer:
C ( I think)
Explanation:
If a chemical reaction requires an energy input rather than releasing energy, then the ∆G for that reaction will be a positive value. In this case, the products have more free energy than the reactants. Thus, we can think of the reactions’ products as energy-storing molecules. We call these chemical reactions endergonic reactions, and they are non-spontaneous. An endergonic reaction will not take place on its own without adding free energy.

A
Female sea turtles develop at higher temperatures.
(Choice B)
B
The sex of sea turtle offspring depends on the incubation temperature.
(Choice C)
C
The largest number of male sea turtles will develop at 28
(Choice D)
D
Most of the sea turtle eggs hatched if incubated at 26
Answer:
Choice B i had this question a long time ago ;)
Explanation:
Answer:
The sex of sea turtle offspring depends on the incubation temperature.
Explanation:
1.) In low incubation temperatures (26°C) and high incubation temperatures (36°C), a large number of sea turtle embryos die.
2.) In temperatures 30°C and below, no males hatch, and in temperatures 34°C and above, no females hatch. This suggests that the sex of the hatchlings is affected by incubation temperature.
3.) The correct answer is: The sex of sea turtle offspring depends on the incubation temperature.
