Read the following selection and answer the question. On a September day in 1999, people began to notice that Lake Jackson in the Panhandle region of northern Florida was shrinking. Within a few days, it was almost gone. A sinkhole had opened beneath the lake and drained it, along with all of its inhabitants including fish and alligators. As aquifers lose water, rock and soil layers can become weaker and less capable of supporting overlying layers of earth and any human structures built upon them. In such cases, the land surface above may subside, or sink. Sometimes subsidence can occur locally and suddenly in the form of sinkholes, which are areas where the ground gives way with little warning. Once the ground subsides, soil becomes compacted, losing the porosity that enabled it to hold water. Recharging a depleted aquifer may therefore become more difficult. Sinkholes occur when?

Answers

Answer 1

Answer:

Sinkholes occur when water from the groundwater has been removed in excess.

Explanation:

Sinkholes are empty spaces in the ground that occur due to the landslide of large volumes of land, creating craters of different sizes. This landslide takes with it everything that is on top of it, such as houses, animals, streets and even entire buildings. While these holes can occur due to engineering flaws, the most common reason is the excessive use of groundwater, which creates an empty space in the interior of the soil and causes the earth to sag.

Choose the combination of factors that creates snow.

Answers

Answer:

Relative Humidity- Low

Air tempurature-cold

Air Pressure-low

Explanation:

High pressure, warm temperatures, and high humidity are  factors that creates snow.

What are the factors that create snow?

Snow and/or ice formation requires temperatures below freezing, both in the atmosphere and close to the ground.

Something that will induce the moist air to rise, forming clouds and precipitation, moisture, produces precipitation and clouds.

Water that has frozen solidly is snow, and the atmosphere (layer of gases around Earth) contains water in the form of vapor (gas). When there is a lot of vapor present, clouds develop, fill up with water droplets, and eventually begin to rain.

Therefore, when a very cold water droplet freezes onto a pollen or dust particle in the atmosphere, a snowflake starts to form.

The exploration of the mid-Cayman rise is intended to discover _______. a. what life may have been like before the evolution of photosynthesis b. the origins of photosynthesis c. life in shallow, coastal regions d. the chemical composition of undersea mountains Please select the best answer from the choices provided A B C D

Answers

Answer: a. what life may have been like before the evolution of photosynthesis

Explanation:

The mid-Cayman rise is an area that has little light coming in but still has life in it.

Plants are able to provide food for themselves and the rest of us by using photosynthesis to make food. Photosynthesis uses sunlight to make this food.

One would think that photosynthesis was around for as long as plants were around but this is not the case. Life on earth had existed long before photosynthesis became a valuable process to plants.

There is therefore curiosity as to how this life fed itself without using photosynthesis and this is why the life in the mid-Cayman is being explored. The way the life makes food there in the absence of light will shed light on how plants made food before photosynthesis.

Entre una planta alta de color purpura (AABB) con otras planta enana de color blanco (aabb), ¿cómo será el genotipo y el fenotipo de la F1 Y F2?

Answers

Answer:

- Alelos:  

Locus 1: A (alto); a (enano)

Locus 2: B (púrpura); b (blanco)

- Cruzamiento parental: AABB  x aabb

Genotipos F1: AaBb

- Cruzamiento F1: AaBb x AaBb

Fenotipo: 100% plantas altas púrpuras

- Genotipos F2:  AABB (1/16); Aabb (1/16); aaBB (1/16); aabb (1/16); AaBb (4/16); AABb (2/16); aaBb (2/16); AaBB (2/16); Aabb (2/16)

- Fenotipos F2: 9/16 A-B- (altas púrpuras); 3/16 A-bb (altas blancas); 3/16 aaB- (enanas púrpuras); 1/16 aabb (enanas blancas)

Explanation:

Un cruzamiento dihíbrido refiere a un tipo de cruzamiento entre dos parentales que difieren para  dos pares de alelos (AABB x aabb). Si consideramos dos loci de dominancia completa, un cruzamiento dihíbrido producirá una F1 heterocigota para ambos genes donde la progenie expresará ambos rasgos dominantes. Como resultado de la distribución independiente expresada en la segunda ley de Mendel, La F2 de este tipo de cruzamiento producirá un proporción fenotípica 9:3:3:1; es decir 9 individuos con ambos rasgos dominantes (A-B-), 3 con el rasgo uno dominante (A-bb), 3 con el rasgo dos dominante (aaB-) y 1 con ambos rasgos recesivos (aabb).

Answers

Answer:

D the rate of growth will slow down by 2100

Explanation:

Sorry if it’s wrong

World's population growth rate will slow down by 2100 in future.

What is world's  population growth ?The rise in the number of people in a population or dispersed group is known as population growth. Global population growth is roughly 83 million people per year, or 1.1 percent per year. From 1 billion in 1800 to 7.9 billion in 2020, the world's population has increased dramatically.

What will be the world's population growth rate in future?The world's population is expected to reach 10.9 billion by 2100 in future, with yearly growth of less than 0.1 percent – a significant decrease from present rates. Between 1950 and today, the world's population increased by 1% to 2% per year, going from 2.5 billion to more than 7.7 billion people.

Hence, the correct option is D.

When DNA code changes, what happens to the protein made?

Answers

This occurs when one nucleotide base is substituted for another in a DNA sequence. The change can cause the wrong amino acid to be produced. In some cases, the change has little effect. In other cases, the incorrect amino acid can affect the structure or function of the protein being encoded. A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein.
