Sex is a biological trait that refers to the observable physical and genetic characteristics that distinguish males from females. It is frequently assumed that sex is based on biological or genetic characteristics rather than social and cultural aspects.

The physical variations between males and females, such as genitalia and breasts, are some examples of sex differences. Thus, it is a biological characteristic rather than a social one. Both social constructionism and biological determinism, on the other hand, have opposing perspectives on gender. Biological determinism emphasizes that gender differences are inborn, while social constructionism emphasizes that they are socially produced. According to the social constructionism perspective, gender identity and the roles associated with it are the product of socialization and cultural expectations, whereas biological determinism focuses on innate biological differences and the impact of biology on gender.

The claim that sex is a biological trait and not socially constructed can be supported by two course materials. The article "Sex as Biological and Gender as a Social Construct" by Anne Fausto-Sterling argues that sex is a biological characteristic because it is based on genitalia and chromosomes, while gender is socially constructed. This article suggests that sex is primarily concerned with physical characteristics, while gender is linked to social and cultural expectations, which is consistent with the idea that sex is biological and gender is social.

Sponges and Cnidarians have a central body cavity and not a digestive system

Explanation:

A gamete is a reproductive cell that combines with another gamete during fertilisation (conception) in organisms that reproduce sexually.

The reproductive cells of an organism are called gametes, and they hold half of the genetic material needed to make a new person.

Male and female gametes in humans are represented by sperm and egg cells, respectively. A new person with a distinct genetic make-up is created during fertilisation when the male and female gametes mix.

Being haploid cells with only one pair of chromosomes, gametes are. The 23 chromosomes in humans make up half of the 46 chromosomes found in somatic (body) cells.

Meiosis, which decreases the number of chromosomes by half, is the procedure used to create gametes. This is crucial for maintaining genetic diversity and avoiding the inheritance of an excessive number of recessive genes by offspring.

Answer:

the kind of material it is moving through

Explanation:

Sound wave is a type of mechanical wave, which requires a medium to travel, unlike longitudinal waves that can travel through vacuums. Since, sound waves travel through mediums, the KIND OF MEDIUM/MATERIAL it is traveling through has a role to play on how fast it moves.

Sound waves move faster in materials whose molecules are closely packed together than those with loosely packed molecules. This is why sound waves naturally travel faster in SOLID materials. Therefore, the the kind of material the sound wave is moving through affects how fast it moves.

Bromine is less reactive than fluorine because it is easier for fluorine to gain an electron.

Elements are atoms with the same number of protons in their atomic nuclei. Elements cannot be broken down into other simpler substances even if they use chemical reactions because they are single substances. Examples of elements are hydrogen, fluorine, iron, oxygen, and calcium.

Electronegativity is the ability of atoms in a molecule to attract electrons to themselves. The greater the electronegativity of an atom, the greater its ability to attract electrons to itself. Flour is a halogen element that has a large electronegativity, very reactive among other groups of elements because it has a small size. So flour is easier to get electrons. While bromine has a large size so it is less electronegative.

Neurotransmitters are received in the dendron and then cause an nerve impulse to be sent along the axon. What word completes the sentence.

The central nervous system can direct the action of muscles in the body through a mechanism known as Neuromuscular transmission (NMT). Acetylcholine (ACh), a neurotransmitter, is released into a muscle cell's junction as a result of nerve impulses.

An axon releases substances known as neurotransmitters when a nerve impulse reaches the end of the axon. Axon and dendrite of the following neuron form a synapse across which neurotransmitters move. To the dendrite's membrane, neurotransmitters bind.

Following binding, the neurotransmitter causes the target cell to undergo a change or take an action, such as sending an electrical signal to another nerve cell, contracting a muscle, or releasing hormones from a glandular cell.

Answer:

A. Mix-matching

Explanation:

Sexual reproduction increases genetic variation in offspring by three main mechanisms: 1-random assortment of chromosomes during meiosis 2-genetic recombination, and 3-random fusion of gametes from different parents. In the first place, the pairs of homologous chromosomes are randomly oriented in metaphase I before they separate in Anaphase I. In consequence, daughter gamete cells receive different combinations of chromosomes. Second, recombination (also called crossing over) refers to the interchange of genetic material between non-sister chromatids during prophase I, thereby also increasing genetic variation in daughter cells. Third, the fusion of two haploid cells (i.e., gametes) in diploid organisms results in the formation of a single zygote cell that develops into a new organism, thereby the process of random fertilization between any two gametes generates different diploid zygotes, increasing thus genetic diversity.

Answer: C >-< sorry if its wrong im like 65% sure

Explanation: im think its C due to the fact that salt water nor any kind of water goes into cytoplasm.

Water is essential for the growth and survival of plants. One of the primary functions of water is to facilitate photosynthesis, the process by which plants produce food and energy from sunlight. Water is absorbed by the plant's roots and transported to the leaves, where it is used to split water molecules into oxygen and hydrogen during photosynthesis. The oxygen is released into the atmosphere, and the energy produced is used by the plant to grow and carry out other essential processes. Without water, plants would not be able to produce the energy they need to survive and thrive.

During interphase of the cell cycle, the cell undergoes a period of growth and DNA replication. The DNA in the nucleus is in a condensed form called chromatin, and it replicates to form two identical copies of each chromosome, known as sister chromatids. These sister chromatids are held together by a protein structure called the centromere.

The nuclear membrane also remains intact during interphase, allowing for proper cell functioning and protection of the genetic material. Additionally, the cell prepares for division by replicating organelles and cytoplasmic components, ensuring that each new cell will have the necessary machinery to function properly.

Overall, interphase is a crucial period in the cell cycle as it allows the cell to prepare for division by replicating genetic material and ensuring proper functioning of organelles. By the end of interphase, the cell is ready to enter the next stage of the cell cycle, known as mitosis or meiosis.

The water flea will compete with native species for food, leading to a decrease in organisms that are important to other species. The Correct option is B

The introduction of spiny water fleas to the lake poses a significant ecological concern. Since they consume zooplankton, which is also a vital food source for native fishes, competition for this shared resource is inevitable. The water fleas will compete with native species for the available zooplankton, resulting in a decrease in the abundance of these organisms.

This can disrupt the food web dynamics and have adverse effects on the population of native fishes and other species that rely on zooplankton as a crucial part of their diet. The spiny water flea's spread through human activities enhances their invasion of new lakes, exacerbating the competition and potential negative impacts. The Correct option is B

The mechanism causes the movement of phloem sap from sources to sink tissues that would be differences in the source-sink pressure potential according to the pressure-flow hypothesis.

As a result of the high turgor pressure, phloem sap is transported by "bulk flow" from the source to the sink, where the sugars are quickly eliminated from the phloem. The rise when the sugar is removed, causes the water to leave the phloem and return to the xylem, lowering the p.

Phloem sap moves through phloem via translocation, the transport of dissolved materials in a plant, which is triggered by high turgor pressure and occurs from source to sink. Phloem carries sap both upward and downward, from sugar sources to sugar sinks, unlike the xylem, which can only carry water upward. It is suggested that the phloem is a conduit through which pressure-containing water-carrying food molecules flow.
