Answer:
20%
Explanation:
Pairing do occur between a purine and a pyrimidine base or a pyrimidine and a purine base where Adenine pairs with Thymine and Guanine pairs with Cytosine.
DNA(deoxyribonucliec acid) sample is usually compose of 100% nucleotide base,
Since 30% of the sample section is compose of thymine then Adenine the base pair will also be 30% this is because adenine will always pair with thymine and each will occur in equal quantity. Together, adenine and thymine compose 60% of the segment.
While the remaining 40% of the section is composed of guanine and cytosine pairs and since the two bases will be equal in quantity, 20% of the DNA section will be cytosine nucleotide.

Answer:
There are two mode of reproduction in living organisms sexual and bisexual reproduction. In Asexual reproduction, fusion of gametes do not take place and have single parent and in sexual reproduction, two parents (male and female) are involved to give birth to new organism.
1. Amoeba : 1 parent ; Asexual reproduction
2. Caraboa: 2 parents; Sexual reproduction
3. Molds: 1 parent: Asexual reproduction and molds reproduce through spores.
4. Strawberry: 1 parent; Asexual reproduction by following vegetative reproduction
5. Yeast: 1 Parent; Asexual reproduction by following the process of budding.

How can you tell the stigma
from the stamens in a tubular insect-pollinated flower
Explanation:
The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules. The male parts are called stamens and usually surround the pistil.
How does the nucleus, cell membrane, and ribosomes work together?
Answer:
Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
OR
In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome. The newly made subunits are transported out through the nuclear pores to the cytoplasm, where they can do their job.
The nucleolus inside the nucleus produces ribosome components, which are synthesized just outside of the nucleus form ribosomes.
The spindle then sends mRNA towards the ribosomes, which is used to code for protein synthesis.
Other organs in the cell, including the mitochondria and lysosomes, are surrounded by lipid membranes that isolate them from other components in the cell.

What is one way to reduce the use of nonrenewable energy resources?
A building additional gas-powered factories in rural areas
B making more efficient gas-powered automobiles
C burning coal instead of wood in a fireplace
D mining for coal instead of drilling for oil
One way to reduce the use of nonrenewable energy resources is that make more efficient gas-powered automobiles. Thus, the correct option is B.
What is a Non-renewable energy resource?A non-renewable energy resource may be defined as a source of natural resources that can not be readily replaced by natural means at a speed quick enough to keep up with consumption. Such types of resources take millions of years to be synthesized.
Burning of coal, mining of coal, building additional gas-powered factories in rural areas, utilization of nuclear energy, etc. are not the measures that are helpful in the reduction of usage of nonrenewable energy resources.
If we want to reduce the usage of non-renewable energy resources, it is required to be less dependent on such resources.
Therefore, one way to reduce the use of nonrenewable energy resources is that make more efficient gas-powered automobiles. Thus, the correct option is B.

Group 1:Hand Sanitizer Bacteria growth:28
Group 2:Soap A. Bacteria Growth:12
Group C: Soap B. Bacteria Growth:13
Group 4: Warm Water. Bacteria Growth:24
Answer:
Independents are all the different liquids used ie: soaps, water, hand sanitizer.
Dependent is the bacteria growth.
Explanation:
This is because you are constantly change the liquids so that is independent. The bacteria growth is dependent since the growth depends on the different liquids.

Protists live in dry environments.
Protists produce their own food from the water.
Protists reproduce asexually or sexually.
Protists live in moist environments.

Explanation:
Some medicines are delivered in capsules or artificial vesicles to be swallowed. Would this method be best for delivering medicines that act on target protein in the plasma membrane,the mitochondria,or the cytosol?
Answer:
the cytoplasm because cytoplasmic enzymes can degrade artificial vesicles such as, for example, lipid-like vesicles. Subsequently, the drug can be delivered at specific cellular locations (including the cell membrane and mitochondria)
Explanation:
The design and development of drug delivery systems is fundamental for the efficiency of the medicine being delivered to the body. Within the cytoplasm, there are specific lytic enzymes that degrade capsules containing medicine (e.g., lipolytic enzymes capable of degrading lipid vesicles). Within the cytoplasm, the drug is delivered to target sites (in this case, the cell membrane or mitochondria) by the activation of different molecular recognition mechanisms.

Fossils help scientists date rocks
Sometimes younger rock layers are found beneath older rock layers
The map of earth has changed over millions of years, but it is now set
No fossils from the Precambrian era have been found because there were no organisms at that time
Answer:
1. True 2. True 3. False 4. False
Explanation:
Fossils help scientist date rocks: Fossil presence is one of the most useful characteristics to date a rock, a fossil will set a specific geological age in which the organisms was present in the world, and vice-versa a new fossil can be dated by studying the age of the rock it was found. Answer: True
Sometimes younger rock layers are found beneath older rock layers: This phenomenon can be found in rock layers near the surface because process such as landslides that happen on the surface moves the surface rocks often resulting in older rocks appearing in the surface and younger rocks being buried by them. Answer: True
No fossils from the Precambrian era have been found because there were no organisms at that time: Although the number of organisms where very little organisms like algae (Stromatolites) were present in this era and fossils can be found. Answer: False
The map of Earth has changed over millions of years: but it is now set: The Earth crust is actually still moving, and will always move due to the tectonic plates and their movement caused by density and pressure, Nowadays The countries have moved from their once mapped location, because of this maps are needed to be updated by new geodesic measurements of the surface. Earth crust moves 2.5 centimeters per year. Answer: False
