Answer:
b. thrive during the summer, when sunlight increases
Explanation:
Phytoplankton production is highly associated with latitude and season. In polar regions, phytoplankton production is reduced to the summer (and eventually spring) season. In consequence, the zooplankton that eats phytoplankton only can survive during the spring and summer seasons. On the other hand, in tropical areas, there exists a nearly constant phytoplankton production all year round.
What can you tell about bacteria that have been Gram stained?
A) Microscopic morphology
B) Macroscopic morphology
C) Gram reaction
D) A and C
Answer:
D) A and C
Explanation:
Gram staining is a laboratory technique used for bacterial species. It is used to differentiate between two groups of bacteria based on the components of their cell wall. Gram staining was developed by a scientist called Christian Gram in the year 1884. In the gram stain procedure, the following occurs:
- Due to the thick peptidoglycan component of their cell wall, GRAM POSITIVE bacteria retains the crystal violet due and stain VIOLET.
- On the contrary, due to the thin peptidoglycan component of their cell wall, GRAM NEGATIVE bacteria do not retain the crystal violet dye and hence stain, RED.
Based on this, a bacteria that has been gram stained has been tested for its GRAM REACTION and microscopic morphological characteristics, since it is a microbe.

Each of the following statements describes a step in the replication of SARS-CoV-2. These steps are listed in random order. Read through the steps and, in the spaces provided below, list them in the order they occur in the human body.
- The virus releases its RNA genome into the cell.
- Viral RNA polymerase helps transcribe more copies of the virus’s RNA.
- The virus binds to a receptor on a human cell’s membrane.
- New viruses travel to the cell membrane of the infected cell and are released outside the cell.
- The virus’s RNA is translated into proteins by the cell’s ribosomes.
Answer:
- The virus binds to a receptor on a human cell’s membrane.
- The virus releases its RNA genome into the cell.
- The virus’s RNA is translated into proteins by the cell’s ribosomes.
- Viral RNA polymerase helps transcribe more copies of the virus’s RNA.
- New viruses travel to the cell membrane of the infected cell and are released outside the cell.
Explanation:
Coronaviruses are viruses from the family Coronaviridae (Order Nidovirales), which are structurally composed of positive-sense single-stranded RNA (ssRNA) genomes with a size of approximately 25 to 33 kilobases. Since the coronavirus genome consists of an ssRNA, they can be directly translated into protein inside infected host cells. The coronavirus that has caused the recent pandemic can enter into host cells through its spike (S) glycoprotein which binds to the Angiotensin-converting enzyme 2 (ACE2) receptor. Subsequently, this virus exploits the host molecular machinery to encode an RNA polymerase which is used to generate RNA from an RNA template. Finally, these RNAs are translated into all viral components (structural proteins) and new viruses are recruited to infected cells.
What is better for a beginners pet leopard gecko or crested gecko
Answer:
leopard gecko
Explanation:
Answer:
you chose based off what i type
Explanation:
crested geckos need a vivarium and a uvb light but turn it off at night cause they are nocturnal they need stuff to climb on a hide and a clean cage the eat a powder mixed with water and crickets you can give them other bugs to they can jump from your hand to your arm if they want to they will drop there tail if scared they do not grow back also super cute
leopard geckos need a 20 gallon or bigger terrarium with uvb to turn off at night and a heat pad 24\7 make sure its no to hot leopard geckos need a variety of bugs like crickets and bubia roaches and other and a clean tank and at least 2 hides they will drop there tail but they do grow back they just look a little different but are super cute
In cats, some are black, some are orange, and some are calico (fur that is both black and orange) All calico cats are always females. This trait represents two inheritance patterns. This two and explain how you know.
please help.
Calico cats are predominantly female because they’re colouring is related to the X chromosome.
Two X chromosomes are needed for a cat to have that distinctive tri-colour coat.If a cat has an XX pair, she will be female.Male cats have an XY chromosome pair, so they can’t be Calicos.Have a great day <3 (I love cats)
Answer: In cats, one of several genes controlling fur color is located on the X chromosome. The gene has two versions, or alleles. One form of the gene codes for orange fur (XB), and the other form codes for black fur (Xb). While it's difficult to say which allele is dominant and which is recessive, since only one is ever expressed (see below), let's say, for the sake of argument, that orange is dominant to black. Ordinarily, this would mean that an animal inheriting one copy of each gene (genotype XBXb) should have orange fur. Surprisingly, a female cat heterozygous at that locus (XBXb) will not be orange. Instead, her coat will be a patchwork of orange and black, a condition known as tortoiseshell. Male color expression is straightforward. Because only one allele exists for the gene in each cell, it will be expressed. And all males have only B or only b. There are no heterozygotes, because the Y does not carry the allele.

Put these statements in correct order to understand how hearing works. - Ions enter hair cells - Stapes moves - auditory cortex recognizes the sounds - hair cells bend - Incus moves - auditory nerve transmits the signal to the auditory cortex - Fluid wave moves across Organ of corti based on frequency - Sound wave enters inner ear - Fluid in the cochlea moves - sound wave is generated from hitting a key on a piano
Answer: From the question,the correct order of how hearing works is listed below:
--> sound wave is generated from hitting a key on a piano,
--> Incus moves,
--> Stapes moves,
--> Sound wave enters inner ear,
--> Fluid in the cochlea moves,
--> Fluid wave moves across Organ of corti based on frequency,
--> Ions enter hair cells,
--> hair cells bend,
--> auditory nerve transmits the signal to the auditory cortex,
--> auditory cortex recognizes the sounds.
Explanation:
In mammal, two ears are present on each side of the head. It is know as the organ for hearing and balance. The ear is divided into three regions:
--> OUTER EAR: This consists of pinna, ear canal, and eardrum( tympanic membrane)
--> MIDDLE EAR: This consists of the ear ossicles ( malleus, incus and stapes).
--> INNER EAR: This consists of Cochlea (organ of hearing) and semicircular canals (for balance).
To explain further on how we hear sounds, the vibrations of sounds produced from an external source move from the outer ear to the middle and then to the inner ear where the cochlea, the organ for hearing is located.
As sound wave is generated from hitting a key on a piano, the pinna collects the sound waves and directs them into the ear canal. Sound waves impinge on the tympanic membrane and makes it vibrate. This causes the malleus, incus and stapes (in this order) to move to-and -fro at the middle ear region.
In the inner ear region, sound wave enters inner ear as stapes pushes the oval window in-and-out. The vibrating oval window causes the fluid in the cochlea( perilymph) to move to-and -fro. Fluid wave moves across Organ of corti based on frequency. The pressure waves in the perilymph push the membrane separating the upper canal and the cochlear duct to-and-fro allowing ions to enter the hair cells. As a result, the hairs of the sensory cells between these two membranes bend causing nerve impulses to be sent to the brain through the cochlear part of the auditory nerve. Auditory nerve transmits the signal to the auditory cortex which recognizes the sounds.
Down syndrome in humans may result from. A a person inheriting a recessive allele. B sickle-shaped cells becoming stuck in blood vessels.c an extra copy of chromosome 21. D blood failing to clot properly.
Complete the following statement from what you have learned about the motor unit. In some neurodegenerative diseases the lower motor neuron cell bodies die and the remaining lower motor neurons sprout processes that innervate the neuromuscular synapses vacated by the dead lower motor neurons. In these muscles, the size of the motor unit ____________ and the strength of the muscle contraction generated by individually activating each surviving motor neuron _________.
Answer:
The correct answer is - increase, increase.
Explanation:
In some neurodegenerative diseases, some lower motor neuron cells die and the remaining lower motor neurons continuing the process of the vacated dead motor neuron cells to innervate the neuron and muscle synapses.
The size of the motor unit increases and due to the innervations of the new axon
increases the strength of the muscle contraction occurred by individually activating each surviving motor neuron. Here multiple motor units will be controlled by a single neuron.

Answer:
B
Explanation:
When detected, ____________ is produced and secreted. Hypoxemia is inadequate oxygen ____________ and can be detected by the kidneys and liver. This will result in an increase of ____________ transport throughout the body. Thus, the correction of hypoxemia is controlled by a ____________ feedback loop. EPO will stimulate the red bone marrow to ____________ RBC
Answer:
erythropoietin; transport; oxygen; negative; produce.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Erythropoietin (EPO) is produced mainly in the kidney in response to cellular hypoxia and it is responsible for the viability, proliferation, differentiation and growth factor of the erythrocytic progenitors.
When detected, erythropoietin is produced and secreted. Hypoxemia is inadequate oxygen transport and can be detected by the kidneys and liver. This will result in an increase of oxygen transport throughout the body. Thus, the correction of hypoxemia is controlled by a negative feedback loop. erythropoietin (EPO) will stimulate the red bone marrow to produce red blood cells (RBCs).

Tina used 500 N of force to move a desk. The desk weighed 300 N, and she
moved it 1.5 meters. How do you calculate the work done by Tina?
A. Multiply 300 by 1.5.
B. Add 500 to 300.
O
C. Multiply 500 by 1.5.
D. Divide 300 by 1.5.
Answer:
The correct answer is - C. Multiply 500 by 1.5.
Explanation:
Given:
Force to move a desk = 500 N
weight of desk = 300 N
displacement = 1.5 meters
work done by Tine = ?
Formula:
work done (W) = F*d
where F is the force applied on the desk and d is the displacement of the desk.
Solution:
As the displacement is perpendicular to the weight of the desk, therefore, the work done by weight is zero. The work done to the displacement of the desk would be =
W = F*d
= 500*1.5
= 750 J
Thus, the correct answer would be option C.

Which of the following flower structures protects the developing flower before the bud opens?
A. sepals
B. petals
C. ovary
D. stame
Answer:
A. sepals
Hope it helps
Please mark me as the brainliest
Thank you
Answer: A. Sepals: These are the small, leaf-like parts growing at the base of the petals. They form the outermost whorl of the flower. Collectively, sepals are known as the calyx. The main function of the calyx and its sepals is to protect the flower before it blossoms(in the bud stage).
Explanation: When a flower is a bud, it is surrounded by sepals, which in many cases are green, as in this example. They protect the flower bud and are behind/underneath the petals when the flower opens. Together, all of the sepals are called a calyx.
Consider a plant with the following characteristics. Round leaves (R) are dominant to pointed leaves (r). White flowers (W) are dominant to pink flowers (w). Plants heterozygous for both traits are crossed. What is the probability of obtaining a plant with pointed leaves and pink flowers
Answer:
.0625 or 6.25%
Explanation:
Find the probability for the plant to have pointed leaves. If the two parent plants are heterzygous, then the likelihood the plant has a recessive characteristic is 25%, 1/4, or .25 for our calculations.Find the probability for the plant to be pink. If the two parent plants are heterzygous, the likelihood the plant has another recessive characterisitc is again 25%, 1/4, or .25 for our calculations.Multiply them together. (1/4)*(1/4)=(1/16) or .0625, or 6.25%Which of the following are true of muscle disorders? Select all that apply.

How can studying the DNA of organisms and their specific genes provide evidence for how organisms change over ?
Answer:
As generations and generations go on there are mutations that cause one or many mistakes while replicating DNA. The genes are expressed and it can be postive (faster organism) or negative (weaker organism). Overtime the mutation can become a new trait and a new species is formed that is slightly differnt from other species. EX penguins species there are King penguin vs little penguin.
