In a strand of DNA, if the percentage of thymine is 30%, what would the percentage of cytosine in the same DNA strand be?

Answers

Answer 1

Answer: 20%

Explanation:

I haven't learned this exactly yet, but if there is 30% of thymine, then there has to be 30% of adenine because they match. That would leave 40% for other Guanine and Cytosine, and since they also match that means that it is exactly half, meaning that there is 20% Guanine and 20% Cytosine.

Which is not true about mitosis A. The chromosomes in the daughter cells are half the number from the parent cell B. The chromosomes in the daughter cells are the same number as the parent cell C. Each nuclei is identical to the parent nucleus D. The four main stages of mitosis are prophase, metaphase, anaphase, and telophase

Answers

The chromosomes in the daughter cells are half the number from the parent cell. So, the correct option is (A).

What is Mitosis?

Mitosis is defined as the part of the cell cycle in which the duplicated chromosomes are divided into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes remains the same. Hence, it is also known as Equilateral Partition.

The phases involved in the mitosis are :-

ProphasePrometaphaseMetaphaseAnaphaseTelophase.

Mitosis occurs in somatic cells which occurs in all types of cells that are not involved in the production of gametes. Each mitotic division contains one copy of each chromosome, thus a complete set of chromosomes is found in the nucleus of each new cell.

Thus, the chromosomes in the daughter cells are half the number from the parent cell. So, the correct option is (A).

Which of the following most likely indicates that a chemical change has
happened?
A. A plate breaks when it falls to the floor.
B. There's a loud sound when a jet airplane starts its engines.
C. An icicle melts in the sun.
D. A can is crushed when it is stepped on.

Answers

Answer:

Option B

Explanation:

A plate breaking when falling to the floor would be a physical change, not chemical, as what the plate is created from would not change.

An icicle melting in the sun would be a physical change, as an icicle is frozen water, and after melting it would be normal water.

A can being crushed is still just a physical change, as the material making the can(typically aluminum) has not changed.

When a jet airplane starts its engines, fuel is combusted, creating energy for the engines to start. This would create the loud noise. As fuel is combusted, it turns into different things, henceforth the sound would imply a chemical change has occurred.

Lentic Systems and give examples

Answers

Answer:

Lentic is a class of aquatic ecosystems that are found on land, such as:

   ponds

   rivers

   lakes

   swamps

   streams

Mostly, lentic ecosystems are described as still bodies of freshwater, and they are smaller ecosystems. Some lentic ecosystems contain animals and microorganisms, but they mostly rely on the photosynthesis of algae and underwater plants to produce energy to thrive. One of the requirements of a lentic body of water is that it is exposed to the sun to encourage photosynthesis.

Explanation:

A lentic ecosystem entails a body of standing water, ranging from ditches, seeps, ponds, seasonal pools, basin marshes and lakes. Deeper waters, such as lakes, may have layers of ecosystems, influenced by light. Ponds, due to their having more light penetration, are able to support a diverse range of water plants.

1. A study was created to test the effects of jazz on people’s sleep patterns. The hypothesis of the experiment was that if people listened to jazz music as they fall asleep, they will sleep for longer periods of time. For the experiment, 2 groups of people were created. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The other group was placed in a room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored.


Dependent Variable: ______________________ Control Group: ____________________________


Independent Variable: _____________________ Experimental Group: _______________________

Answers

Answer:

Independent variable: Jazz

Dependent variable: Amount of time used to sleep

Control group: The group that was placed in a quiet room

Experimental group: The group that was placed in a room where jazz music played softly

Explanation:

In an experiment, the independent variable refers to the variable being changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment, the independent variable is the JAZZ used.

Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the AMOUNT OF TIME SPENT SLEEPING.

Control groups are the groups in an experiment that do not receive the experimental treatment (jazz music). Hence, the GROUP THAT WAS PLACED IN A QUIET ROOM is the CONTROL GROUP.

Experimental group, on the other hand, is the group that receives the experimental treatment in an experiment. In this case, the experimental group is the GROUP THAT WAS PLACED IN A ROOM WHERE JAZZ MUSIC WAS PLAYED SOFTLY.

How do organisms survive if the cells they are made of continually die?​

Answers

Answer:

nope.................................

every cell in your body is over 3 billion years old.

The strategy that multicellular organisms such as humans use to project themselves into the future is to create new cell colonies from a single undifferentiated cell rather than maintaining existing colonies indefinitely. The main reason is that reproduction is more flexible and robust than maintenance, and it provides a way of starting over with a “clean slate” and slightly different genes. Complex organisms accumulate billions of errors and problems over their lifetime. So basically organisms survive because new cells are made everytime a cell dies.

(Choice D) D It is an anabolic reaction.

Answers

Answer:

The correct answer is - (Choice A) A It is a catabolic reaction.

Explanation:

The catabolic reaction is a reaction that involves the sepration of larger molecules into smaller molecules and releases the energy stored in the chemical bond.

This metabolic reaction breaks the larger molecules into smaller and simple molecules for example in cellular respiration glucose molecule is broken down into water and carbon dioxide and releases energy in the form of ATP.

Answer: D- It is an anabolic reaction.

Explanation: This reaction is anabolic, since it consumes energy to build a more complex molecule from smaller ones.

Answers

The stomach and small intestines absorb the glucose and then release it into the bloodstream. Once in the bloodstream, glucose can be used immediately for energy or stored in our bodies, to be used later.
Glucose comes from the Greek word for "sweet." It's a type of sugar you get from foods you eat, and your body uses it for energy. As it travels through your bloodstream to your cells, it's called blood glucose or blood sugar.

The top of the saturated zone is known as A. the aquifer B. the water table C. the unsaturated zone D. spring rock​

Answers

Answer:

B. the water table

Explanation:

The question above is related to the topic on "Groundwater."  

Groundwater is considered "fresh." It falls into the soil and gets soaked in it. It can stay stored for many years. It is very beneficial because it serves as a source of water for many residential places.

The storage of groundwater relies on two zones: unsaturated zone and saturated zone. The unsaturated zone is the first layer under the surface area of the land. It is followed by the "water table," which lies a little farther from the land surface. After which is the saturated zone where you can find particles of different rocks.

The top of the saturated zone is known as the water table. Therefore, option (B) is correct.

The water table divides the saturated zone, where water fills the crevices between soil or rock particles, from the unsaturated zone, which is air-filled. Precipitation, groundwater exploitation, and seasonality affect the water table. It controls groundwater supply and flow.

Spring or surface water bodies can form where the water table meets the land. Managing water supplies, analysing groundwater flow patterns, and assessing groundwater contamination require water table monitoring.
