Answer:

25 degree celcius

Explanation:

formula

(given degree Fahrenheit - 32)×5÷9

(77 - 32)× 5÷9

= 25°C

Here I will show you how to convert 77 F to C so you know how hot or cold 77 degrees Fahrenheit is in Celsius. The F to C formula is (F − 32) × 5/9 = C. When we enter 77 for F in the formula, we get (77 − 32) × 5/9 = C.

so therefore the answer is 25 degrees celsius

Answer: The question is incomplete and the options are not given but here are the options gotten from another websites.

A. Narrow part.

B. Wide part

C. The flow rate are the same in both part.

The correct option is C.

The flow rate are the same in both part.

Explanation:

The flow rate are the same in both because when there is partial blockage at the artery wall, the blood flow speed will reduce or stop, therefore the blockage will be a barrier or hindrance to free blood flow and therefore, both the narrow part and wide part will receive the same level of blood flow because of the blockage and this blockage result in restricted blood flow which in one way or the other hinder oxygen supply to the heart. The blockage deposits can cause a thickened artery wall and when blood flow is restricted it causes chest pain and if it stop it can cause heart attack. Blockage deposits can be as a result of artery wall damage.

In the experiment, two factors changed throughout the course of the study: the genes of the parental mice and the fur color of the offspring.

The genes of the parental mice: The experiment involved studying the genetic makeup of the parental mice, specifically focusing on the alleles responsible for fur color. The researchers likely examined the genes of the parental mice to determine which alleles they carried and how they could potentially be passed on to their offspring. By studying the genetic composition of the parental mice, the researchers could track the inheritance pattern of the fur color trait.

The fur color of the offspring: The primary objective of the experiment was to investigate how fur color is inherited in mice. To achieve this, the researchers likely observed and recorded the fur color of the offspring produced by the parental mice.

As the experiment progressed and new generations of mice were born, the researchers would have noticed changes in the fur color of the offspring. By comparing the fur color of the offspring to the known genetic makeup of the parental mice, they could analyze the inheritance patterns and determine whether specific alleles were dominant or recessive.

Temperature regulation is the human condition chosen for this project. The human body must maintain a core body temperature of around 37°C, despite environmental temperature changes. The following information answers the questions:

Factors that can shift the body temperature include exposure to hot or cold environments, fever, and physical activity.

The organ systems involved in the homeostasis process of temperature regulation are the nervous and endocrine systems, as well as the integumentary (skin), cardiovascular, and respiratory systems.

Negative feedback is used to maintain temperature homeostasis. For example, when the body temperature rises, the hypothalamus signals the sweat glands to secrete sweat, which cools the skin and lowers the body temperature.

The stimulus is the change in body temperature, the receptor is the thermoreceptor in the skin or hypothalamus, the integrating center is the hypothalamus, the effector is the sweat glands or muscles, and the response is sweating or shivering.

Strategies to help maintain temperature balance include wearing appropriate clothing, using heating or cooling devices, and maintaining physical fitness through exercise.

Answer:

Answer:

Explanation:

A more diversity by the amount of species and even distribution of said species.

Answer:

In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled.

The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).

The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.

Since the DNA cannot leave the nucleus , copies of the section needed to make the protein are made, this is called transcription.

This done by first opening the double helix with an enzyme called DNA Helicase. Another enzyme called RNA polymerase will match new bases to the original DNA attaching them in a long strand of mRNA. When the enzyme reaches the end the strand will be removed and the DNA can close.

The correct ranks of the nucleic acids structures in order of size from smallest to largest is b)Chromosome-gene-codon-nucleotide. So, option b is correct.

Nucleic acid structures design alludes to the construction of nucleic acids like DNA and RNA. Synthetically speaking, DNA and RNA are basically the same. Nucleic acids design is frequently separated into four distinct levels: essential, auxiliary, tertiary, and quaternary.

Essential design comprises of a direct succession of nucleotides that are connected together by phosphodiester bond. This straight arrangement of nucleotides make up the essential construction of DNA or RNA. Nucleotides comprise of 3 parts:

    1. Nitrogenous base

   2.Thymine (present in DNA as it were)

   3.Uracil (present in RNA as it were)

5-carbon sugar which is called deoxyribose (tracked down in DNA) and ribose (tracked down in RNA). At least one phosphate groups.

Hence, option b is correct.

Complete question:

In a population of flowers growing in a meadow, C1 and C2 are autosomal codominant alleles that control flower color. The alleles are polymorphic in the population, with f (C1) = 0.7 and f (C2) = 0.3. Flowers that are C1C1 are yellow, orange flowers are C1C2, and C2C2 flowers are red. A storm blows a new species of hungry insects into the meadow, and they begin to eat yellow and orange flowers but not red flowers. The predation exerts strong natural selection on the flower population, resulting in relative fitness values of C1C1 = 0.30, C1C2 = 0.60, and C2C2 = 1.0. Assuming the population begins in H−W equilibrium, what is C1 allele frequency after one generation of natural selection? Express your answer using three decimal places.

Answer:      

The C1 allele frequency after one generation of natural selection equals 0.559

Explanation:

Due to technical problems, you will find the complete answer and explanation in the attached file.    

Explanation:

RNA growth is always in the 5′ → 3′ direction: in other words, nucleotides are always added at a 3′ growing tip, . Because of the ANTIPARALLEL nature of the nucleotide pairing, the fact that RNA is synthesized 5′ → 3′ means that the template strand must be oriented 3′ → 5′.

Answer:

L allele: 0.575 (or 57.5%)

l allele: 0.425 (or 42.5 %)

Explanation:

Homo-zygous individuals have two copies of the same allele (i.e., either L alelle or l allele), while heterozygous individuals carry both alleles at a time (i.e., one L allele and one l allele). In consequence:

- Frequency of the L allele: [(450 x 2) + 250] / 2000 = 0.575

- Frequency of the l allele: [(300 x 2) + 250] / 2000 = 0.425

The statements that are true about the esophagus are:

The esophagus is the muscular tube of the digestive tract that develops from the pharynx to the stomach.

This part of the digestive system is traversed by food, which enters through the mouth, passes through the pharynx, crosses the esophagus and reaches the stomach.

In this process, the esophagus has an active participation, since its walls contract to promote the advance of the food.

Therefore, we can conclude that the esophagus is a muscular tube that moves food from the mouth to the stomach.

These phases are prophase, prometaphase, and metaphase,  Cytokinesis is the final physical cell division and is considered the sixth phase of mitosis.

Cytokinesis begins in the phase of cell division. and ends in telophase, extending completion as the next interphase begins. The first obvious change of cytokinesis in an animal cell is the sudden aspect of a pucker, or cleavage furrow, on the cell surface.

Mitosis and each of the two meiotic divisions result in two unrelated nuclei contained within a single cell. Cytokinesis performs a crucial process to separate the cell in half and ensure that one nucleus ends up in each daughter cell.

So we can conclude that Cytokinesis, the division of the cytoplasm to form two new cells, overhangs with the final stages of mitosis.
