Answer:

first Q answer is

smooth muscle

second Q answer is

striated

third Q answer is

skeletal

Smooth muscle is responsible for contractions of the digestive tract and arteries. Cardiac muscle, which has branched fibers, is responsible for heart contractions. Skeletal muscle, attached to bones, facilitates voluntary movements.

The type of muscle responsible for contractions of the digestive tract and arteries is smooth muscle. Cardiac muscle is unique in that it is composed of branched fibers. Whereas, the muscle type that is attached to bones is known as skeletal muscle.

Smooth muscle tissue contraction is responsible for involuntary movements in the internal organs such as the digestive system, arteries, and other hollow organs, while cardiac muscle is responsible for the contraction of the heart and is marked by striated, branched fibers. On the other hand, skeletal muscles are also known as voluntary muscles because they are under our conscious control and are attached to the skeleton, enabling bodily movements.

Answer:

The correct option is B, PYRUVATE CARBOXYLASE.

Explanation:

Gluconeogenesis is the process by which the body produce glucose from non-glucose precursors in the body. The gluconeogenesis pathway usually become active when there is shortage of glucose in the body. The enzymes that carry out the process of gluconeogenesis can be found mostly in the cytosol; only one of them is present in the mitochondria. The gluconeogenesis enzyme that is found in the mitochondria is PRUVATE CARBOXYLASE.

Answer:

The neurons interact with each other at synapse through action potential generated in response to the stimulus. At the resting phase, all the ion channels remain closed and the cell maintains a high amount of Na⁺ ions outside the cell and a high amount of K⁺ ions inside the cell. This difference maintains the membrane potential at -70mv.

When a stimulus activates a cell receptor, it causes the opening of the sodium channels in response to either mechanical stimulus or neurotransmitter released due to stimulus. The opening of the sodium channels leads to the influx of  Na⁺ ions which changes the potential from -70 mv to more positive value. When this change in membrane potential reaches - 55 mv it leads to the opening of the voltage-gated channels which causes an influx of Na⁺ ions. This more influx of  Na⁺ ions leads to depolarization when the membrane reaches above the threshold and the action potential is generated in the neuron.

Answer:

1. Increase

2.  Decrease

Explanation:

During inspiration, diaphragm contracts and lowers down. There is a simultaneous contraction of external intercostal muscles and movement of rib-cage upward and outward. All these events lead to an increase in the volume of the thoracic cavity. Increase in volume of the thoracic cavity results in expansion of lungs and lowering down the air pressure within alveoli of lungs.

The contraction of the respiratory diaphragm and intercostal muscles during inhalation increases thoracic volume and decreases pressure in the lungs, causing air to enter.

When the respiratory diaphragm contracts, it flattens, leading to an increase in thoracic volume. Concurrently, the intercostal muscles pull the ribs up and out. Owing to Boyle's Law, which posits an inverse relationship between pressure and volume, this increase in thoracic volume leads to a decrease in pressure within the lungs as compared to the external atmosphere. As a result, air is drawn into the lungs.

Answer:

The sympathetic nervous system

Explanation:

Betty's successful escape was facilitated by the activation of the sympathetic division of the autonomic nervous system, which triggers the fight-or-flight response necessary for such quick, survival-oriented actions.

During the incident where Betty outran her assailants, the part of her nervous system that was most directly responsible for her successful escape was the sympathetic division of the autonomic nervous system. This system is key to initiating the fight-or-flight response when faced with a perceived threat. The sympathetic nervous system rapidly activates to prepare the body to either confront or escape danger by increasing heart rate, dilating bronchi, dilating pupils, activating sweat glands, and directing blood flow to essential muscles for immediate action.

Answer: External validity.

Explanation:

When any research is done, then there are two possibility of its validation. One is internal validation and other is external validation.

The internal validation refers to the condition in which the conclusion of the study is within context of the particular study.

The external validation refers to the condition in which the conclusion of the study is out of the  context.

Here, The study was performed only on the eating disorders in the adolescent boys but the conclusion included other males of different age groups.

Dr. Tylka's conclusion that her research findings on the risk of developing eating disorders in adolescent boys can be generalized to other contexts indicates she believes her findings have high external validity.

Dr. Tylka is stating that her findings have high external validity. This term refers to the extent to which the conclusions drawn from a particular study can be generalized, or extended, to other settings, populations, or times. The generalizability of a study's results is an important aspect of its external validity. It relies on the use of valid survey questions which accurately measure what they are intended to measure, and reliable survey questions that consistently produce similar results across different instances to ensure a lack of bias.

Dr. Tylka's confidence in her research suggests that she believes her study's constructs and their measurement methods, including the survey questions, have been well designed to accurately represent and assess the risk of developing eating disorders among adolescent boys. This assurance further implies that these methodological tools are likely to yield similar findings if used in different contexts, which strengthens the claim of high external validity.

Answer:

Cleavage, morula, blastocyst, gastrula

Explanation:

The zygote is formed after fertilization of sperm and ovum. Then the zygote undergoes a repeated cell division to form a number of cells. These tiny cells formed by mitotic cell division but present inside the zygote. It forms 2 cells then 2 cells, then 8 cells and so on. After forming the number of cells the zygote has a number of tiny cells. This stage is called morula and the tiny cells are called morulae. Then these cells migrate towards the periphery of the morula and creating a central space called blastocoel. This hollow ball structure is known as the blastocyst. After this blastocyst stage, the cells migrate to form 3 layers such as endoderm, mesoderm, ectoderm. From this layer different organs are formed. This 3 layered stage is known as gastrula. Thus the zygote development starts from cleavage, morula, blastula, and gastrula.

The correct developmental order from a zygote to an embryo is cleavage, morula, blastocyst, and gastrula, which involves cell division and restructuring into layers.

The correct sequence of development from a zygote to an embryo is as follows: cleavage, morula, blastocyst, gastrula. Initially, the zygote undergoes rapid cell division known as cleavage, forming smaller cells called blastomeres. This process leads to the formation of a morula, which is a solid ball of cells.

Following this, the structure develops into a blastocyst, which has a distinct inner cell mass and is surrounded by an outer layer of cells.

Finally, gastrulation occurs, where the blastocyst reorganizes into a gastrula with different layers that will develop into various tissues and organs of the embryo.

They need to be cut or cleaved by restriction enzymes called endonucleases in a way that both source and vector are left with complementary DNA strands for ligation using DNA ligase enzymes

Confirmation bias may be defined as a type of cognitive bias in which the hypothesis is confirmed by the over weigh evidence. The under weigh evidence are rejected in this confirmation bias.

The confirmation bias mainly focuses on the the observation that can support the hypothesis. Later, the research can prove to be incorrect based on the hypothesis in the confirmation bias.

Thus, the answer is confirmation bias.

Answer:

True

Explanation:

One of the most important theories in forensic science is regarding the Principles of Trace Evidence.

Explanation:

When you make the cross. You get

HH HH Hh Hh.

So the genotypic ratio - 2:2 which is also 1:1.

The phenotypic ratio - 4. Since Hh and HH are horned organisms. So they only differ in their genotypic make up.

The cross between a homozygous dominant (HH) and a heterozygous (Hh) horned organism results in offspring with a 3:1 genotype ratio of HH to Hh but a 100% horned phenotype.

Understanding the transmission of traits requires knowledge of genetics. In the given cross between a homozygous dominant (HH) horned organism and a heterozygous (Hh) horned organism, we can predict the genotype and phenotype probabilities of their offspring.

Steps for Calculating Probabilities:

List the possible gametes each parent can contribute. The HH parent can only contribute H gametes, while the Hh parent can contribute both H and h gametes.

Construct a Punnett square to determine possible offspring genotypes. The combinations can be HH and Hh.

Identify genotype and phenotype ratios. The HH genotype will display as horned, and so will the Hh genotype.

As a result, we can expect a 3:1 ratio of HH to Hh genotypes in the offspring. However, since both genotypes exhibit horns, we will see a 100% horned phenotype among the offspring. It's important to note that test crosses are typically used to determine genotypes of dominant expressing individuals when crossed with a homozygous recessive individual, which is not the case in this scenario.

Answer:

There will not be any effect because the body will continue to produce enough.

Explanation:

Producing breast milk to satisfy a starving newborn is an arduous and energy-intensive task - about 500 calories a day. Therefore, it is important that moms a little more than normal. If the mother eats little, her body will still produce good quality milk, but she will run out of energy. This can also slow the recovery of your body after childbirth.

What determines milk production is how often the baby breastfeeds or how much more the mother empties her breasts. That is, the more the baby suckles, the more milk the mother will have. This milk will always be the amount of nutrients a baby needs, regardless of whether or not the mother has eaten. But if the mother does not eat, she may have health problems.

If a breastfeeding mother isn't able to eat enough food, the quantity of her breast milk may decrease slightly. However, her body will typically prioritize the nutrition of her breast milk to ensure the baby receives what it needs. Over time, however, the mother's health and potentially the nutritional quality of the milk can be affected.

In conditions of nutritional shortage, a woman's body will prioritize the production of breast milk to ensure the baby receives necessary nutrients. The quantity of milk may slightly decrease, but the body makes significant efforts to maintain its nutritional quality. However, prolonged periods of inadequate nutrition might impact the overall milk quality and the availability of nutrients for the lactating mother.

Lactation is the process by which milk is synthesized and secreted from the mammary glands in response to an infant's demand. During breastfeeding, hormones such as prolactin and oxytocin, along with growth hormone, cortisol, parathyroid hormone, and insulin, are active. These hormones facilitate the transport of maternal amino acids, fatty acids, glucose, and calcium to breast milk. Even with a decreased food intake, a lactating mother's body will strive to provide adequate nutrition for the baby by using stored fat reserves.

The initial breast milk known as colostrum is thick and yellowish, high in proteins but contains less fat and glucose. As the lactation continues, mature milk is produced with different composition. It's important to note3hat the composition of breast milk can also slightly change based on the mother's diet and nutritional status.

While the mother's health may be at risk due to inadequate nutrition, the body prioritizes milk production to ensure infant health. However, over time, malnutrition can affect both the mother's health and potentially the nutritional quality of the breast milk.
