Which of the following tissues does not provide support in flowering plants?
A. Collenchyma
B. Parenchyma
C. Xylem
D. Phloem
Answer: B
Explanation: it says which one does not provide, collenchyma does provide support.
The tissue which does not provide support in flowering plants is parenchyma. The correct option is b.
What is parenchyma?Parenchyma is a type of simple permanent tissue that makes up a major part of ground tissues in plants, where other tissues like vascular tissues are embedded. They are non-vascular and composed of simple, living and undifferentiated cells, which are modified to perform various functions.
The main characteristics of parenchyma are, They are living permanent tissues that can divide at maturity and help in the regeneration and healing of wounds, Parenchyma cells are the foundation of a plant as reproductive cells are parenchymatous, Single parenchyma cells of a zygote can develop into an entire plant. These cells are called “totipotent” cells, Parenchyma cells occur in the form of continuous masses as homogeneous parenchyma tissues e.g. in the pith and cortex of stems and roots, mesophyll of leaves, the flesh of succulent fruits and in the endosperm of seeds.
Parenchyma cells may be associated with other types of cells to form heterogeneous complex tissues such as the parenchyma of the xylem and phloem.

During replication, enzymes called ____________________ untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the _______________________.
Answer:
During replication, enzymes called helicases untwist the double helix, separating the two parental strands. The point at which the two chains separate is known as the replication fork.
Explanation:
Replication is the process of multiplication of DNA molecules where, from one molecule, two molecules with the same information as the original can be obtained.. Each new replicated DNA molecule has an original strand and a new strand, so replication is semi-conservative.
For replication to occur, the double strand of DNA must be separated, a process that requires the participation of a group of enzymes called helicases. The helicases are responsible for breaking the hydrogen bonds between the complementary bases of one strand and another.
The DNA strands, when separated, form a zipper-like image, and the point of separation between the two is called the replication fork.
The study of genes is called genetics.

This chart shows the temperature in the clouds and the temperature in the air below the clouds for different cities. In which city would sleet likely be observed?
A) Houston
B) Seattle
C) Nashville
D) Detroit
Answer:
B. Seattle
Explanation:
"Sleet" occurs when a warm air intrudes between the clouds and the ground. During precipitation, a "snow is formed." This is because of the freezing cold temperature in the clouds, just like Seattle that has a freezing cold temperature of -5°C. Once it falls down, it reaches a warmer temperature, just like the temperature below the clouds in Seattle that is 3°C. This melts the snow and starts to refreeze again once it reaches the surface of cold air on Earth. This forms the "sleet."
I think it might be B
My explanation is that sleet happens when a kind of warm air gets in between clouds and the ground, while precipitation, a kind of snow is formed and this is because of the cold temperature in clouds when it is cold like maybe -4°C if it falls down the temperature becomes warmer, This soon melts snow and then with cold air you get Sleet!
Hope this helps!

When economic conditions are favorable, more effort can be put into synthetic materials that satisfy desires and not just needs.
O True
O False
Answer:
True
Explanation:
The correct answer would be true.
A favorable economic condition in an area means that a large percentage of the population of the people in the area already have their basic needs met. According to Abraham Maslow, when basic needs are met, human needs graduate from basics to more sophisticated ones. Consequently, production efforts can be put into producing material that satisfies desires and not just needs.

Which statement below is an example of how a gamete's
structure significantly helps its function?
Eggs have tails to help them travel down the fallopian tubes to the uterus.
Sperm have a well-protected head and a motor to help them travel.
Eggs are small to minimize their chances of double fertilization.
Sperm are large so that they can contain nutrients for the developing embryo.
Answer:
Sperm have a well-protected head and a motor to help them travel.
Explanation:
Gametes are sexual cells. Organisms make use of gametes to sexually reproduce themselves. Male organisms produce gametes called SPERM while feale organisms produce gametes called EGG. Although both of these gametes function to sexually reproduce the organism that produces them, they have different morphological characteristics that supports their physiological function.
- The sperm cell is made up of two major parts namely: the head and the tail. The head of the sperm cell contains the nucleus, which houses the genetic material of the cell i.e. DNA. For this reason, the head is well protected. Also, the sperm contains a tail region, which is actually a flagellum that enables it to be motile i.e swim through the female reproductive part. The flagellum contains a structure called AXONEME, which is referred to as the MOTOR of the sperm cell.
Help!!! look at the picture!
Answer:
The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.
Explanation:
Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.
Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.
When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.

The STARTING molecule for the Krebs cycle is
A.)NADH
B.)pyruvic acid
C.)glucose
Answer:
B
Explanation:
This combines with a 4 carbon compound to start the cycle
Kreb's cycle or Tricarboxylic cycle is an enzyme-catalyzed reaction, in which ATP molecules are generated. The starting material for the cycle is pyruvic acid.
The correct answer is:
Option B. Pyruvic acid
Some of the features of Kreb's cycle are:
The starting material of Kreb's cycle is pyruvic acid. The pyruvate is obtained from the glycolysis of glucose molecules.The pyruvic acid breaks into a two-carbon molecule and joined with the enzyme Co A, to form a two-carbon molecule Acetyl Coenzyme A.The Krebs cycle is a series of dehydration, reduction, oxidation, and hydration reactions.The product of Kreb's cycle is two carbon dioxide molecules, one GTP, and reduced NADH and FADH2.
Thus, the starting material for the Kreb's cycle is pyruvic acid, which is converted into the acetyl Coenzyme A before entering the Kreb's cycle.
