what best describes a tetrad
Answer :
4 chromatids.
Explanation: the world needs answers , I can provide
Tetrad is best described by two sister chromatids, coming together to form a four-part structure.
A tetrad, also known as a bivalent, is a structure that forms during meiosis I in sexually reproducing organisms.
During prophase I of meiosis I, homologous chromosomes pair up and become physically connected along their lengths.
This connection between homologous chromosomes is called synapsis.
As a result of synapsis, a tetrad is formed, which consists of two pairs of sister chromatids, one pair from each homologous chromosome.
The tetrads play a crucial role in the process of genetic recombination or crossing over. During prophase I, while the tetrads are formed, the genetic exchange can occur between the non-sister chromatids of the homologous chromosomes.
Thus, a tetrad is a four-part structure formed by two pairs of sister chromatids that come together during meiosis I.

It takes a 1.5 m length of 137 cm-wide fabric to make the collar of an airbag
manufacturer is making 250 special-order collars. One morning, at
only 65% of the length of fabric they need to make the collars. How ma
are needed to be able to make all 250 collars? Show your work.
ke the collar of an airbag helmet. The
One morning, a technician finds they have
ollars. How many more meters of fabric
Answer:
163 fabric needed to make 250 collars.
Explanation:
Given that,
Length = 1.5 m
Width =137 cm
Number of order = 250
Use fabric = 65%
We need to calculate the actual length need to make a collar
Using given data
[tex]Actual\ length =Length\times use\ fabric[/tex]
Put the value into the formula
[tex]Actual\ length =1.5\times\dfrac{65}{100}[/tex]
[tex]Actual\ length=0.975\ m[/tex]
We need to calculate the total length of fabric
Using formula for total length
[tex]total\ length=Actual\ length\times Number\ of\ collars[/tex]
Put the value into the formula
[tex]total\ length=0.975\times250[/tex]
[tex]total\ length=243.75\ m[/tex]
We need to calculate the number of fabric
Using formula for number of fabric
[tex]Number\ of\ fabric=\dfrac{total length}{length}[/tex]
Put the value into the formula
[tex]Number\ of\ fabric=\dfrac{243.75}{1.5}[/tex]
[tex]Number\ of\ fabric=162.5\approx 163[/tex]
Hence, 163 fabric needed to make 250 collars.

If 5 ml of amylase, an enzyme which digest carbohydrates, is added to a vial with 10 ml of water and 10 ml of sucrose. At the end of the reactions, how much amylase do you expect to find in the vial?
Answer:
5ml
Explanation:
Enzymes are protein molecules that act as biological catalyst in living systems, as they help speeden up the rate of biochemical reactions. However, one unique characteristics possessed by enzymes unlike substrates is that they do not get used in the reaction. Instead, they are released from the substrate-enzyme binding after the reaction and can be recycled.
Hence, in a case whereby 5ml of amylase, an enzyme that breaks down carbohydrates, is added to a vial containing 10 ml of water and 10 ml of sucrose. The amount of amylase expected to be in the vial at the end of the reaction is 5ml because it will not get used up during the reaction. Hence, the volume of enzyme remains constant after reaction.

Please select the best answer from the choices provided
Ο Α
ов

Answer:
An organism that eats another organism is called a consumer.
Explanation:
In food webs, consumers are characterized by not being able to produce their own nutrients, having to acquire them from the consumption of other living beings.
Consumers are found from the second level of the food web and can be primary consumers, or herbivores, and secondary, tertiary or even quaternary consumers, who are carnivores.
The other options are not correct, due to:
a. Vertebrate : which has an internal skeleton, of a bony or cartilaginous nature.
c. Invertebrate: lack of internal skeleton and spine
d. Embryo: is the product of fertilization, whose development occurs in the uterine cavity or inside an egg.

"Explain the process of how the human circulatory system delivers blood that is rich with oxygen to all parts of the body and then returns the blood to the lungs and completes this cycle over and over"
"List 5 senses and how does the nervous system including the brain and spinal cord play a part in the process of each of these 5 senses."
"Please compare and contrast the difference between photosynthesis and cellular respiration. Please include glucose, water, oxygen, carbon dioxide and the sun"
Answer:
The circulatory system of our body complies with the gas exchange in the pulmonary alveoli, there the oxygen enters and binds to a protein which oxidizes it, this protein is allosteric, and it is called hemoglobin, this hemoglobin travels the human body capturing every need punctual of each organ, some organs will demand more or less oxygen according to the metabolic state of the human system.
Once oxygen is in front of an organ with few partial pressures of oxygen, it is released from the hemoglobin and this protein changes its conformation and then re-oxidizes when passing through the pulmonary alveoli.
It is important to clarify that hemoglobin is found in red blood cells, and these in the blood where they are pumped and distributed by the cardiovascular system.
Sense of taste, smell, touch, hearing and sight.
In the spinal cord, it is related more than anything those touch receptors in charge of executing reflexes against injuries or harmful conditions, such as touch receptors that are in charge of measuring temperature and measuring the limb's withdrawal response to excessive heat or burn .
As for the central nervous system and the cortex, they are responsible for managing the signals sent by sensory neurons, associating them with feelings, memories and experiences, such as taste and smell.
Photosynthesis is a process where energy currency for plants is obtained as a product, it requires ultraviolet light and carbon dioxide as products, where plant chlorophyll intervenes and oxygen is released to generate food autonomy for plants.
On the other hand, the respiratory chain is a process where proteins are oxidized sequentially to allow the gas exchange of those living organisms.
Explanation:
Explanations one and three are related because they both explain breathing methods in plants and animals such as humans, while in question two the human nervous system is related to the perception of the environment through the senses.

Scientists have concluded that human activities are affecting the atmosphere and causing rapid climate change on a global scale. Which statement provides the strongest evidence that these changes to global climate are NOT the result of natural causes, such as variations in Earth's orbit? 1 point Until recently, Earth's climate had remained relatively constant. Variations in Earth's orbit cannot be measured precisely. Variations in Earth's orbit would affect climate only minimally. Earth's climate depends mostly on the output of the sun. Variations in Earth's orbit occur gradually over 100,000 years.
Answer:
Earth's climate had remained relatively constant.
Explanation:
Scientists have established that human-based activities have affected and are affecting a rapid change in the earth's climate as they have brought about massive changes in the global carbon cycles and affected the ecological systems. Earth is has an ever-changing climate and the variation in the orbit of earth results in natural changes such as seasons, which depend on the duration and intensity of the sunlight.During mitosis the chromosomal number is...
