how are logistic and exponential growth similar?

Answers

Answer:

because both are same words

Explanation:

Answer:

Both growth models begin with a population that is growing at a constant rate.

Logistic growth follows a period of exponential growth, as population growth slows or stops.

Exponential growth is only possible when resources are unlimited.

Logistic growth shows what happens when resources become scarce and population growth slows.

1. The parts of the flower involved in reproduction are ________ and __________
2. The anthers bear the ___________the microspore mother cells give rise to _______or pollen grains after meiotic cell division.

Answers

Answer:

1. Stamen and pistil

2. Pollen, microspore

Explanation:

The flower is the reproductive part of certain plants called ANGIOSPERMS. They make use of their flower for sexual reproduction. The different parts of the flower work together to achieve a common goal, which is to reproduce, however, they do it in various ways. For example, accessory parts like petals attract pollinators. The major parts of the flower that are directly involved in the reproductive act are STAMEN (male) and PISTIL (female).

The stamen which constitutes a structure called ANTHER bears the pollen grains or microspore, which is made when the microspore mother cells undergo meiotic division. Hence, the pollens are released from the anther of a male flower (stamen), into the stigma of the female flower (pistil).

If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?

Answers

Answer: 4 Guanines

Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.

We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.

The DNA is a double-stranded molecule, which is made up of purine, pyrimidine, a pentose sugar, and phosphate backbone. Chargaff's rule states that any species will have a stoichiometric ratio of 1:1.

The number of guanines in the double-stranded DNA is 4.

In the DNA, the base pairing occurs as:

The guanines bind with cytosine through hydrogen bonding. The adenine binds with thymine with two hydrogen bonds.

In the given nucleotide, there are 23 purines (guanine and adenine). There are 15 thymines in the DNA molecule.

Based on the Chargaff rule, the 15 thymines will bind to adenine, leaving only 4 guanines and 4 cytosines. Thus, there will be 4 cytosines left to bond with the guanines to achieve Chargaff's ratio of 1:1.

Therefore, the guanine in the nucleotides will be 4.

Briefly explain how genes affecting a polygenic characteristic are located with the use of QTL mapping.

Answers

Answer:

QTLs can be identified by using molecular markers associated with the variation of the trait

Explanation:

A Qualitative Trait Locus (QTL) is a chromosomal region correlated with the variation of a quantitative trait, i.e., a phenotypic trait controlled by many genes. QTL mapping refers to the identification of QTLs associated with a particular trait. In QTL mapping, molecular markers (i.e., small and identifiable DNA fragments) are used to develop genetic linkage maps which are further used to discover QTLs. This technique (QTL mapping) consists of evaluating the phenotypic segregation of the trait in the progeny by statistically correlating phenotypes with patterns of genetic segregation (segregation of the molecular markers).

What structure provide shape and support for the cell?
A.Chloroplast
B.Mitochondria
C. cell Wall
D.Golgi bodies

Answers

the answer is cell wall :)

The cell wall provides shape and support for the cell. Therefore, option (C) is correct.

What is cell wall?

In the cells of plants, fungi, and some bacteria, the cell wall is a strong structure that encloses the cell membrane. It has a solid and strong structure because it is formed of chitin, which is found in fungi and cellulose in plants. The cell wall supports it mechanically, shields it from harm, and aids in keeping its shape. Moreover, it stops the cell from bursting or collapsing under pressure, which is crucial for plant cells because they must maintain turgor pressure in order to function properly.

Animal cells, on the other hand, lack a cell wall and instead contain a cytoskeleton formed of protein fibers that gives them stability and shape. Organelles that perform photosynthesis include chloroplasts, mitochondria, and golgi bodies, which also produce energy and process and transport proteins inside of cells.
