Answer:
Trachea
Explanation:
The laryngeal reflex occurs and it is present in babies after birth. When water occupies or enters the mouth, the laryngeal reaction is triggered. While your infant is underwater, the glottis and epiglottis shut, keeping water from penetrating the throat(larynx and pharynx) and establishing a watertight barrier to the lungs. This is so to prevent the aspiration of water into the lungs.

Which statement is true of human cultures? O A. All human societies share the same cultural traits and practices. O B. Every human has a unique set of cultural traits and practices. O C. Culture includes a society's knowledge, customs, and achievements. O D. Cultures are groups of people united by blood relationships. SUBMIT
Answer:
B. Every human has a unique set of cultural traits and practices.
Explanation:
Culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
This ultimately implies that, culture are acquired and passed from one generation to another.
A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication.
This ultimately implies that, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.
Hence, the statement which is true of human cultures is that every human (race) has a unique set of cultural traits and practices that were acquired from the environment and society.
Assume similar data for the motion of the blood in a carotid artery which connects the aorta to the brain. Estimate how many beats of the heart it will it take the blood to get from your aorta to your brain. (Assume that the distance from your aorta to your brain is 30 cm.)
Answer:
4 beats
Explanation:
The number of beats of the heart that will take blood from Aorta to The Brain
n = Distance from Aorta to brain / distance per beat
Given that distance per beat = 7.5 cm ( calculated value outside scope of question using the data attached below)
n = 30 cm / 7.5 cm
= 4 beats

Alleles are described as ____________________. homologous chromosomes homologous chromosomes alternate versions of a gene alternate versions of a gene alternate phenotypes alternate phenotypes environmental factors that affect gene expression
Answer:
The correct answer is - alternate versions of a gene.
Explanation:
In a cell, if there are two copies of each chromosome, these are called homologous chromosomes, one come from the father and the other comes from the mother, which helps in promoting the variety and stability of a species.
Different or alternate versions of genes are possible that can result in two phenotypes for the same trait, these alternate versions called alleles. Alleles can be dominant and recessive.

What is the mechanism by which binding of testosterone to the testosterone receptor leads to upregulated gene transcription
Answer:
This binding causes a conformational change in the receptor which enters into the nucleus and binds DNA to activate transcription
Explanation:
Testosterone is a steroid hormone responsible for inducing protein synthesis and growth of tissues with androgen receptors. Testosterone receptors, also known as androgen receptors, are a class of nuclear receptors activated by binding androgenic hormones (e.g. testosterone) in the cytoplasm, whose binding induces a conformational change of the receptors that are subsequently translocated to the nucleus. Within the cell nucleus, these activated receptors form homodimers that bind DNA in order to promote the transcription of target genes capable of regulating cell growth, cell cycle progression and survival.

Predict a change in the Earth's surface or effect observed at each of the following for
1 point each:
- TRANSFORM BOUNDARY
- DIVERGENT BOUNDARY
- CONVERGENT BOUNDARY
Answer:
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range, which extends from the Arctic Ocean to beyond the southern tip of Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth. The rate of spreading along the Mid-Atlantic Ridge averages about 2.5 centimeters per year (cm/yr), or 25 km in a million years. This rate may seem slow by human standards, but because this process has been going on for millions of years, it has resulted in plate movement of thousands of kilometers. Seafloor spreading over the past 100 to 200 million years has caused the Atlantic Ocean to grow from a tiny inlet of water between the continents of Europe, Africa, and the Americas into the vast ocean that exists today.

Rheumatoid arthritis is commonly associated with the presence of rheumatoid factor autoantibodies in the bloodstream. This indicates that rheumatoid arthritis is likely to be a. an infective process. b. caused by bacterial infection. c. an autoimmune process. d. because of an enzymatic defect.
Answer:
The correct answer is - c. an autoimmune process
Explanation:
Rheumatoid arthritis is a disease or condition that affects the joints mainly by swollen, and painful joints. It is an autoimmune disease as the person's own immune system attacks the body.
The presence of rheumatoid factor autoantibodies states that it is an autoimmune process. There are other autoantibodies also associated with this type of arthritis that are rheumatoid factors (RF), anti‐keratin antibodies (AKA), anti‐filaggrin antibodies (AFA), and anti‐perinuclear factor (APF).
Describe the processes that turn metamorphic rock into igneous rock and the energy that powers the processes.
So, we know that a metamorphic rock is either an igneous or a sedimentary rock that are exposed to intense heat and pressure.
But when the metamorphic rock is thrusted deep underground through subduction, it will again be subjected to intense heat. This can cause it to melt, turning it into a magma. When the magma cools down, it again becomes an igneous rock and the rock cycle continues.

Explanation:
Both microscopy and motility agar are used to confirm microbial mobility. Research techniques involving microscopic determination of mobility and explain why both microscopy and motility agar are required to determine motility in some microbes.
Answer:
One allows microbe to move in the medium and the other allows to see it.
Explanation:
Both microscopy and motility agar are required to determine motility in some microbes because both substances helps to find out the mobility in the microbes. Motility agar is the medium that allows microbes to swim if they have flagella in their body while on the other hand, microscope is used to see the movement of microbes in motility agar. Microbes are small creature which can't be seen through naked eyes so we used microscope for it.
A segment of a DNA molecule has the base sequence ATGAAC. Write a shorthand structure for this segment and for its complementary strand, using the symbols D for deoxyribose and P for phosphate.
Answer: See attached picture.
Explanation:
DNA or deoxyribonucleic acid is the name for the molecule that contains the genetic information in all living things. This molecule consists of two strands that wind around each other to form a double helix structure.
The basic unit of nucleic acids are called nucleotides, which are organic molecules formed by the covalent bonding of a nucleoside (a pentose which is a type of sugar and a nitrogenous base) and a phosphate group. So each nucleotide is made up of a pentose sugar called deoxyribose, a nitrogenous base which can be adenine (A), thymine (T), cytosine (C) or guanine (G) and a phosphate group.
What distinguishes one polynucleotide from another is the nitrogenous base, and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information, following the following criterion of complementarity: A-T and G-C. So the sequence of these bases along the chain is what encodes the instructions for forming proteins and RNA molecules. In living organisms, DNA occurs as a double strand of nucleotides, in which the two strands are linked together by connections called hydrogen bridges.
The chemical convention of naming the carbon atoms in the pentose nucleotide pentose numerically confers the names 5' end and 3' end ("five prime end" and "three prime end" respectively). The 5'-end designates the end of a DNA strand that coincides with the phosphate group of the fifth carbon of the respective terminal deoxyribose. A phosphate group attached to the 5'-end allows the ligation of two nucleotides; for example, the covalent bonding of the 5'-phosphate group to the 3'-hydroxyl group of another nucleotide, to form a phosphodiester bond.

During frog gastrulation, involution occurs at the Group of answer choices endometrium. blastopore blastocoel. trophoblast. archenteron.
Answer:
blastopore
Explanation:
Involution is the second stage after invagination during frog gastrulation. Involution occurs at the blastopore when the marginal zone cells get to the tip of the blastopore, make an inward turn and then move along the inner exterior of the outer cells sheets.
This means that the cells found at the lip of the blastopore and always undergoing change and the first of these cells to develop into the dorsal lip are the endodermal cells. Next are the mesoderm cells that form the Notochord.

Ecologists are interested in quantifying different kinds of biodiversity. In below study outlined here, which kind of biodiversity are ecologists studying?
Ecologists establish 20 small areas, called plots, randomly scattered across a California grassland. They count the number of different plant species present in each plot. By noting how many species appear in the plots, the ecologists are able to estimate the number of species in the entire grassland.
a. Genetic diversity
b. Functional diversity
c. Ecosystem diversity
d. Species diversity
Answer:
d. Species diversity
Explanation:
The species diversity can be measured by:
Species richness: Refers to the number of species are inhabiting a defined area. Species abundance: Describe the distribution of the species abundance.Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region or any well-defined spatial unit. It is a metric for measuring biodiversity which simplicity and easy interpretation make it a standard metric. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
