Dogs have 39 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each dog cell? 19 19.5 23 39 46
Answer:
39
Explanation:
Answer:
39
Explanation:
The cells copy themselves so there is one original and one new. We only count the new so it is still 39.

You have been provided with a non-polar liquid and are trying to determine whether
it is hydrophilic or hydrophobic. You place one milliliter of the substance into a
beaker filled halfway with water. Describe what will happen next.
Answer:
Explanation:
Non-polar liquids are liquids that have covalent bonds in which the shared electrons are shared equally. The molecules of these liquids are repelled by the molecules of water and hence do not dissolve in water. Thus, non-polar liquid are hydrophobic (water dislike/insoluble in water).
When one milliliter of the substance is placed into a beaker filled halfway with water, the substance will be seen "compact" (not dissolving nor interacting) in the beaker of water.
Polarity is defined as the separation of electric charge in a molecule or having an electric dipole moment due to the difference between negative and positively charged ends.
In the given experiment when one milliliter of the substance into a beaker is filled halfway with water, the substance will be seen as coagulating or not dissolving in the water.
The non-polar are the compounds or liquids that do not dissolve in the water. The non-polar molecules are the molecules, which are attracted to the alike molecules, rather than the water molecules.
The non-polar compounds have covalent bonds, in which the electrons are shared among the atoms of the compound.
The molecules of these liquids are repelled in the presence of water or are hydrophobic. These liquids do not dissolve in water.
Therefore, the liquid is hydrophobic.

An on-going research study has been tracking the dietary preferences of gorillas in the wild. Researchers are hoping to formulate a diet for gorillas in captivity that mimics those living in their natural habits. By reproducing the preferred diet, researchers hypothesize that the eventual release back into the natural habitat will be an easier transition for the gorillas.
Researchers are using various methods to make observations and collect data about the feeding habits of gorillas in the wild. Which method would be classified as direct observation?
A) Counting and classifying the debris in the area where the gorillas live.
B) Observing the gorillas from a protected location and recording what they eat.
C) Surveying the natives in the area about the diet of the local gorilla population.
D) Photographing the habitat of the gorillas in a before and after scenario and seeing what is missing from the after photograph.

What is the memory device for the 3 differences between DNA and RNA?
First of all, the nucleotides of DNA and RNA are different: in DNA, in fact, pentose sugar is deoxyribose, while in RNA it is ribose, which has one more oxygen atom. Moreover, in DNA the nitrogen bases are adenine, cytosine, guanine and thymine while in RNA instead of thymine there is the uracil base

The type of stem cell that gives rise to red and white blood cells is called a hematopoietic stem cell and is present in Option C, as hematopoietic stem cells are multipotent stem cells that reside in the bone marrow.
What is a hematopoietic stem cell (HSCs) ?
Hematopoietic stem cells are a type of stem cell that give rise to all types of blood cells, including red blood cells, white blood cells, and platelets, and they reside in the bone marrow and are responsible for replenishing the body's blood cells. They have the ability to differentiate into a variety of cell types, and the process by which HSCs differentiate into the different types of blood cells is tightly regulated by various factors, including growth factors.
Hence, the type of stem cell that gives rise to red and white blood cells is called a hematopoietic stem cell and is present in Option C.

what is the biodiversity score of farmland (maize)?
Answer:
Required Answer:-The intensification of agriculture has caused dramatic declines in farmland biodiversity (Carvalheiro et al., 2013; Senapathi et al., 2015). Since the 1990s, agricultural policies have been developed in Europe to mitigate this loss through agri-environmental schemes (AES). One AES is “sown wildflower strips”, the aim of which is to create new ecological infrastructures by sowing attractive wild flowers on arable land (a few % of the cultivated area). These ecological infrastructures fall within our definition of MIMS since they represent a massive introduction of managed species in the landscape.

O TAT GGG GTA
O UAU CGT GTU
Answer: B: UAU CGU GUA CAU
Explanation:
UAU CGU GUA CAU is the mRNA sequence transcribed from this segment.
What is mRNA?
Single-stranded RNAs of the type known as messenger RNA, or mRNA, are used to make proteins. mRNA is created during transcription from a DNA template.
The function of mRNA is to transport protein information from DNA in a cell's nucleus to the cytoplasm, or watery interior, where the machinery responsible for making proteins reads the mRNA sequence and converts each three-base codon into an amino acid that belongs in a protein chain that is expanding.
Therefore, UAU CGU GUA CAU is the mRNA sequence transcribed from this segment.

1- Evaporation:-
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. For more evaporation, the area that surrounds the surface of the water must be less humid i.e. it should not already be concentrated have the water vapors. For the evaporation we need to increase the temperature of the molecules of water on the surface, which is caused by the Sunlight.

Why is a red laser pointer an example of a poor blackbody radiator?
A. It glows less brightly as electromagnetic radiation is released.
O B. It gives off a range of wavelengths of electromagnetic radiation.
C. It gives off only one wavelength of electromagnetic radiation,
D. It keeps the same temperature and gives off no electromagnetic
radiation
A red laser pointer is a poor blackbody radiator because it emits electromagnetic radiation at only one wavelength. So, the correct option is C.
What is blackbody radiator?Depending on its temperature, a blackbody radiator is an object that radiates at different wavelengths. Blackbody radiation is the radiation that a blackbody radiator emits, and it exhibits a certain pattern known as Planck's law.
A red laser pointer, on the other hand, produces a narrow, focused beam of light at a specific wavelength, typically around 650 nanometers. This indicates that, unlike a blackbody radiator, a laser pointer does not generate radiation at different wavelengths. A red laser pointer is therefore a subpar blackbody radiator.
Therefore, the correct option is C.

What types of solid waste do you produce in your home ?what could be done to each type and what goes to the disposal site or dumpsite
Answer:
Types of solid watse we produce in your home is plastic cups, metal forks and spoons, and also glass plates. We could recycle these items, so they can become other new items when we are finished.
Solid waste are described as abandoned waste materials resulting from human and chemical activities. Solid wastes could include used plastic materials, rubber, metals, glass and other materials classed as useless.
In Homes, solid wastes usually include used plastic, shattered glass, metal objects and so on. Plastic wastes and metals could be recycled and refined to make rubber and aluminium spare parts, hence, serving as raw materials.Therefore, since solid materials take very long to Decay, hence recycling of the waste and their use in organic products are always good means of disposal.
