Explanation:
Generally, oligosaccharides are short chains of polysaccharides/carbohydrates. They make up the structure of membranes including the plasma membrane. Oligosaccharides attached to the protein content of the cell membrane to form a substance called GLYCOPROTEIN. The attached oligosaccharides functions in the ability for a cell to recognize another cell.
According to this question, if an animal whose cell is lacking oligosaccharides on the external surface of its plasma membrane, the most likely impairment would be that of CELL-CELL recognition.
Oligosaccharides are a type of carbohydrates that contain the combination of a few monosaccharides. The are also found as part of the components of the membrane.
If an animal cell lacks this type of carbohydrates (oligosaccharides), the function impaired would be the cell-cell communication function.
Oligosaccharides performs various functions as part of the component of the plasma membrane. It functions in cell to cell recognition and binding and communication. They usually contain 3-10 sugar units (monosaccharides).Learn more: https://brainly.com/question/22301340
Pleaseeee help!!! (psychology edge) Androgens and estrogens are hormones that impact the sexual response cycle. Write about the four phases of that cycle and explain how the two types of hormones are involved.
Answer:
Females and males each have some amount of the sex hormones, androgens and estrogens. In males however, androgens like testosterone is more dominant and in females estrogens like estradiol are more dominant. The hormones both affect the sexual response cycle. The sexual response cycle has four phases: desire, arousal, orgasm and resolution. The desire phase can last anywhere from a few minutes to hours and includes physical changes like an increase in muscle tension, heartbeats quickening, flushed skin, and an increased flow of blood to genitals. The arousal phase extends to the brink of the orgasm phase, during this phase the changes experienced in the desire phase are intensified along with blood pressure increasing. The orgasm phase generally only lasts a few seconds and is the climax of the sexual response cycle, some characteristics include: Involuntary muscle contractions and spasms, blood pressure, breathing, and heart rate at their highest point, a release of built up sexual tension, and flushed skin. During the resolution phase the body returns to normal, often a sense of wellbeing and fatigue is achieved. To begin the cycle a male need a certain amount of the androgen, testosterone, but high levels in females tend to lead to more sexual thought and desires, typically though, women have relatively low levels of testosterone. In women, estrogens, such as estradiol are more common. Estrogens are produced when a girl starts puberty and helps her reproductive cycle begin. A high level of estrogen in men can lead to a reduced sex drive, loss of hair, or trouble focusing, but a normal level in men is crucial to proper erectile function.

What is Renewable resources?A natural resource that can be replenished to replace the portion used up by usage and consumption is known as a renewable resource, furthermore known as a flow resource. This replenishment can occur naturally through reproduction or through other recurring processes in a limited amount of time on a human time scale.
Renewable energy is generated by renewable resources that replace themselves more quickly than they are used up. Examples of these sources that are continuously replenished are the sun and the wind.
Solar energy, wind, falling water, geothermal heat from the soil, biomass from plants, waves, ocean currents, temperature variations in the oceans, and tide energy are all examples of renewable resources.

How are the endoplasmic reticulum and Golgi apparatus
similar?
Both contain their own kind of DNA.
O Both are made up of membranes consisting of a lipid bilayer.
O Both are involved in producing chemical energy for the cell.
O Both are found only in plant cells and not in animal cells.
Answer:
Both are made up of membranes consisting of a lipid bilayer.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.
Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
Golgi apparatus is like a packaging unit because it prepares the protein for export by chemically tagging them.
Also, the endoplasmic reticulum is like an assembly line because it is where the ribosomes perform their tasks.
Hence, the endoplasmic reticulum and Golgi apparatus are similar because both are made up of membranes consisting of a lipid bilayer.
(Q002) Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living non primate animal that is also a biped. Then, compare its bipedalism with our bipedalism. Try to consider how it moves and some of its possible adaptations (such as limb length). Use resources in your classroom, credible online sources, or books to help you if necessary.
Answer:
One good example of a living non-primate that is also a biped is a Kangaroo. With so much power in their legs and vertebral column like humans, kangaroos are biped, but they leap rather than walk. Their legs are usually bigger than their arms, which enables them to push their whole body off the ground.
However, kangaroos are not just bipedal or quadrupedal but they are both. They also hop bipedally like rodents and many birds, with some displaying skipping gaiety. In addition, chimpanzees, gorillas, gibbons, macaques, capuchins, birds, many lizards, and (at their highest speeds) cockroaches run bipedally.
Explanation:
Bipedalism is the use of two feet for standing and walking. Nearly all primates are capable of bipedalism, although most of the primates spend their time on all fours. Primates are known to move bipedally, but they also use bipedalism to stand up on their hind legs to reach food, look for predators, and for social display and communication.

Gregor is planting pea plants in his backyard. Some of the plants are tall and the rest are short. Some of the plants are yellow and the rest are green. The numbers of different plant types are in the ratio[{Tall green}:{Tall yellow}:{Short green}:{Short yellow} = 8:5:2:1. If there are 1080 green plants, then how many total plants are in Gregor's yard?
Answer: 1732
Explanation:
infer short, yellow are recessive
8TG, 5Tg, 2tG, 1tg
proportion of green plants = 10/16
so total plants = 1080*16/10 = 1732

The replication of the given DNA strand TAT-TAG-ATT-ACA is ATA-ATC-TAA-TGT.
What is DNA replication?DNA replication may be defined as a type of biological process through which the genomic DNA of an organism gets copied into the cell during the time of cell division. During this process, the two identical replicas of DNA are produced from one original DNA molecule.
According to the context of this question, when it comes to DNA replication, adenine is replaced by thymine and vice-versa while guanine is replaced by cytosine and vice-versa. So, the amount of adenine remains equal to the amount of thymine and the amount of guanine remains equal to cytosine.
Therefore, the replication of the given DNA strand TAT-TAG-ATT-ACA is ATA-ATC-TAA-TGT.

XX=Female XY=Male.
your best friend has five children and they are all boys. They are expecting their 6th child. What would be the probability for their 6th child to be a girl? Why
Answer:
50% or 1/2
Explanation:
The probability of their 6th child being a girl would be 50% or 1/2.
During meiosis, the female produces X eggs while the male produces X and Y sperms. A random fusion of gametes then occurs during fertilization.
XX x XY
XX (female) XY (male) XX (female) XY (male)
XX - 1/2 or 50%
XY - 1/2 or 50%
Hence, the probability of producing a girl is 1/2 or 50% irrespective of the number of kids a couple might have produced already.
