1.Ovulation
2.Implantation
3.Zygote
4.Fetus
5.Conception
6.Embryo
7.Trimesters
Explanation:
Implantation is a procedure where a developing embryo, moving as a blastocyst through an uterus, reaches the uterine wall and stays connected to it until birth.
embryo is an unborn posterity of a warm blooded creature, specifically an unborn human infant over about two months after origination.
Zygote is a diploid cell coming about because of the combination of two haploid gametes,
Trimester is a time of a quarter of a year, particularly as a division of the length of pregnancy.
Conceiving is the action of conceiving a child or of a child being conceived. Conception is the time when sperm travels up through the vagina, into the uterus, and fertilizes an egg found in the Fallopian tube. Conception — and ultimately, pregnancy — can involve a surprisingly complicated series of steps
In females , implantation is the phase of pregnancy at which the incipient organism holds fast to the mass of the uterus. At this phase of pre-birth improvement, the conceptus is known as a blastocyst. It is by this grip the incipient organism gets oxygen and supplements from the mother to have the option to develop.
Ovulation is the name of the procedure that happens for the most part once in each menstrual cycle when hormone changes trigger an ovary to discharge an egg. You can possibly end up pregnant if a sperm prepares an egg. Ovulation as a rule happens 12 to 16 days before your next period begins. The eggs are contained in your ovaries.
Fetus: A living being in the beginning times of development and separation, from preparation to the start of the third month of pregnancy (in people). After that point in time, an incipient organism is known as a baby.

why are humans called heterotrophs
Answers
Humans are heterotrophs because we depend on preformed organic molecules from other organisms for energy and building blocks for growth. We can't produce our own food through photosynthesis.
Humans are called heterotrophs for several reasons. Here are the key points:
We are totally dependent on preformed organic molecules from food to meet all our energy needs.We also require organic molecules as building blocks for our anabolic processes.Heterotrophs, including humans, cannot produce their own food through photosynthesis; instead, we must consume other organisms.The term 'heterotroph' comes from Greek roots meaning 'other feeder', indicating that our food comes from other organisms.All food consumed by humans can be traced back to autotrophs like plants, which produce organic molecules through photosynthesis.Having a thick cartilaginous plate between two longitudinal bones is a characteristic of which age group?

Select the reason inhalants are most likely abused.
Answers
Answer: They are readily available
Explanation:
Inhalants are most likely abused due to their accessibility, low cost, the lack of stigma associated with their use, and the quick, intense high they offer. They are common household items that when inhaled, provide effects similar to alcohol, a factor that also contributes to their abuse.
Explanation:Inhalants are most likely abused for a multitude of reasons, primary among them being their ease of accessibility and the quick, intense high they provide. Inhalants are usually common household items like glue, paint thinners and hairspray, making them readily available and easy to acquire. Further, they are inexpensive and often not seen as 'drugs' in the traditional sense, reducing the stigma associated with their use.
When these substances are inhaled, they produce effects similar to alcohol, such as feeling euphoric, lightheaded, and experiencing hallucinations. The effects are immediate and intense but short-lived, often leading to repeated abuse in quick succession.

Respiratory organs have large surface areas. how is this an advantage to an animal?
Answers
Final answer:
The large surface area of respiratory organs such as lungs and gills in animals is an advantage as it allows for efficient gas exchange of oxygen and carbon dioxide, which is essential for survival, particularly in larger or more active animals that have high oxygen demands.
Explanation:
The high surface area of respiratory organs is crucial for ensuring efficient gas exchange. In larger animals, specialized organs such as lungs, gills, and intestines have evolved to increase the surface available for the exchange of oxygen (O₂) and carbon dioxide (CO₂). This large surface area, akin to the size of a handball court, enables effective intake of oxygen required for cellular processes.
In addition, complex organisms often possess a sophisticated circulatory system to transport gases from these respiratory surfaces to the cells throughout the body. For instance, the human lung contains numerous alveoli and alveolar sacs that significantly increase the surface area for gas exchange, critical for meeting the oxygen demands of the body, especially in high-energy consuming activities like flight.
Monica's ultrasound reveals that the baby she is carrying is a boy. which chromosome pair is present in her baby?
Answers
XY
A human baby’s gender is determined by the sperm that fertilises the egg cell. A chromosome from the sperm cell which is either X or Y, fuses with the X chromosome in the egg cell. The baby will be a girl if an X chromosome fuses with the X chromosome in the egg cell or it will be a boy if a Y chromosome fuses with the X chromosome in the egg cell which means the females carry XX, and the males carry XY. From the question above, Monica is carrying a boy so the XY chromosome pair is present in her baby.

Cells harvest energy from food molecules by _____. photosynthesis respiration fermentation the Calvin cycle
Answers
Cells harvest energy from food molecules through the process of cellular respiration. Therefore, option B is correct.
What is cellular respiration?Cellular respiration is the process by which cells convert glucose and oxygen into energy in the form of ATP (adenosine triphosphate). It is a metabolic process that occurs in both plants and animals and is essential for the survival and functioning of cells.
The process of cellular respiration involves three main stages: glycolysis, the Krebs cycle, and the electron transport chain. During glycolysis, glucose is broken down into two molecules of pyruvate, which are then converted into acetyl CoA and enter the Krebs cycle.
The Krebs cycle generates ATP through a series of chemical reactions. The electron transport chain uses the energy from these reactions to create a proton gradient, which is used to produce additional ATP. Therefore, option B is correct.

If the sequence of bases in one strand of dna is tagcct, then the sequence of bases in the other strand will be
Answers
Final answer:
The sequence of bases in the complementary DNA strand to TAGCCT is ATCGGA, following the base pairing rules where A pairs with T, and C pairs with G, and considering that DNA strands are antiparallel.
Explanation:
Given the sequence of bases in one strand of DNA as TAGCCT, we can determine the sequence of bases in the complementary strand by understanding base pairing rules. In DNA, the bases pair up according to specific rules where adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). The two strands of DNA are antiparallel, which means they run in opposite directions, with one strand running in the 5'-3' direction and the complementary strand running in the 3'-5' direction.
Therefore, to get the sequence of the opposite strand running from 5' to 3', we'll reverse complement each nucleotide of the given sequence:
Thymine (T) would pair with adenine (A)Adenine (A) pairs with thymine (T)Guanine (G) pairs with cytosine (C)Cytosine (C) pairs with guanine (G)Thymine (T) would pair with adenine (A)Thus, the complementary sequence to TAGCCT running 5'-3' is ATCGGA.

What layer of the rainforest do gliding leaf frogs live in?
Answers
Rainforests are forests characterized by high rainfall, A typical tropical rainforest has a number of layers, namely: emergent, canopy, understory and forest floor layers.
The emergent layer is characterized by a small number of very large trees called emergents, which grow to a height of 45–55 meters. The canopy layer contains the majority of the largest trees, from 30 meters to 45 meters (148 ft) tall. And the densest areas of biodiversity like the gliding frogs live in this layer. The night-active gliding leaf frog gets its name from its ability to glide from branch to branch of the trees in the rainforest canopy. They spread their webbed toes wide apart as a sort of parachute, keeping them aloft as they leap in search of food.
The third layer is the understory or understorey layer which lies between the canopy and the forest floor. The leaves are much abundant at this level so insect life is abundant, too.
The forest floor is the bottom-most layer which receives only 2% of the sunlight. Only a few plants are adapted in here. It contains decaying plant and animal matter, which disappears quickly because of the warm, humid conditions.
A student added an enzyme to a flask containing a substrate and placed the mixture over a flame. She observed the reaction for a few minutes when she noticed that the reaction appeared to have stopped. She was puzzled because there was still a large amount of substrate left in the reaction flask. A pH test confirmed that the pH of the solution was in an acceptable range. Which is the most likely explanation for the decreased reaction rate?
Answers
The rate of the enzymic reaction depends on pH, concentration of substrate, enzyme molecule concentration and the temperature. With the increase of temperature, the rate of the enzymic reaction also increases. But this only happens up to a certain point. After a certain temperature, the rate becomes to decrease and eventually will stop. This is because denaturing of the enzyme. Although other factors are perfect, the high temperature causes to break down of bond interactions and hence the active site will be changed. If the active site of an enzyme changed, then substrate cannot bind with that enzyme anymore.
The temperature which the rate of the reaction is maximum is called optimum temperature and it normally around 40°C. This can be varied from enzyme to enzyme
