Triangle ABC is reflected across line L to form ΔALBLCL, and AAL intersects line L at point D. Which equation is not necessarily true?
A.
m∠ACB = m∠ALCLBL
B.
AD = ALD
C.
m∠BAC = m∠BLALCL
D.
ALD = BLD
Answer:
The equation that is not necessarily true is D. ALD = BLD. This is because the line of reflection (L) does not necessarily bisect the triangle ABC, so the lengths of ALD and BLD may not be equal.

Carmen conducted an experiment to determine if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. Each person listened to seven different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30-second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music
What can Carmen do to make her experiment more reliable?
A. add another variable to test
B. repeat the experiment several times
C. decrease the amount of time the test subjects are exposed to the music
D. putting each test subject in a different location while they listen to the music

you have heard that increasing carbon dioxide concentrations in the atmosphere are leading to ocean acidification. You have also seen the equation for this reaction, wherein increasing CO2 reacts with H20 to form carbonic acid. In your virtual lab you have been provided with a sample of ocean water, a pH meter, and a straw. The straw lets you blow your exhaled CO2 into the water, creating bubbles of CO2 that will mix with the ocean water.
As written in the question the level of carbon dioxide in sea water increases which is wrong because the level of carbon dioxide in sea water is not increasing directly it is increasing because the amount of carbon dioxide in the atmosphere increased.
What is Carbon dioxide?Carbon dioxide is defined as the chemical compound that is made up of molecules each containing a carbon atom covalently linked to two oxygen atoms found in the gaseous state at room temperature. In air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas.
In the virtual lab, we will have to blow the [tex]CO_2[/tex] we exhale into sea water using a straw which will create bubbles of [tex]CO_2[/tex] that will mix with the sea water. A pH meter will then be used to measure the acidity of the sea water.
So, as written in the question the level of carbon dioxide in sea water increases which is wrong because the level of carbon dioxide in sea water is not increasing directly it is increasing because the amount of carbon dioxide in the atmosphere increased.

Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes.
What are the functions of genes?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
Our genes carry information that gets passed from one generation to the next. For example, genes are why one child has blonde hair like their mother, while their sibling has brown hair like their father.
The gene is considered the basic unit of inheritance. Genes are passed from parents to offspring and contain the information needed to specify physical and biological traits.

Imagine you were going to model the flow of energy in an ecosystem and the flow of elements in the ecosystem using a diagram. Compare and contrast your diagrams for these two systems.(site 1)
Only 10% of energy is transmitted from one trophic level to another, whereas proteins, carbs, and lipids are transferred. Producers capture energy, which is subsequently distributed in a linear fashion from one tropic level to the next.
What is flow of energy in an ecosystem?In food webs, energy is transmitted from producers to consumers between the species. Organisms utilise the energy to complete difficult activities. The process of photosynthesis in plants transforms solar energy, which makes up the vast majority of the energy in food webs, into chemical energy.
The interactions, or food chains, between the living organisms that make up an ecosystem determine its trophic levels. In a food chain, energy moves from one trophic level to the next.

options
1.Logistical Growth
2.Linear Growth
3.Exponential Growth
Logistical growth pattern occurs under ideal conditions where organisms have no competition for space, mates or resources.
What do you mean by logistical growth?A logistic function or logistic curve is a common S-shaped curve with equation where x_{0}, the x value of the sigmoid's midpoint; L, the supremum of the values of the function; k, the logistic growth rate or steepness of the curve.
Logistic growth takes place when a population's per capita growth rate decreases as population size approaches a maximum imposed by limited resources, the carrying capacity( K).
Logistic population growth occurs when the growth rate decreases as the population reaches carrying capacity. Carrying capacity is the maximum number of individuals in a population that the environment can support.

What is osmosis?Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane.
If a cell is placed in a saltwater solution, it means the concentration of the solute outside the cell is more than that of the cell.
As a result, water will leave the cell (higher concentration) to the extracellular salt solution. It can be said that the salt solution is hypertonic.

How do the products of photosynthesis relate to the reactants of cellular respiration?
A: They are the same compounds
Or
B: They are different compounds
The products of photosynthesis relate to the reactants of cellular respiration in the sense that: They are the same compounds. Option A is the correct answer.
What is photosynthesis?This refers to the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
The products of photosynthesis (glucose and oxygen) are the reactants of cellular respiration (glucose is broken down to release energy, and oxygen is required for the process).
Nearly all the oxygen in the atmosphere is due to the process of photosynthesis. If photosynthesis ceased, there would soon be little food or other organic matter on Earth, most organisms would disappear, and Earth's atmosphere would eventually become nearly devoid of gaseous oxygen.
