A student claims that the Y chromosome contains the sex-determining region gene, known as the SRY gene, which causes male fetuse

s to develop testes.
Which of the following provides correct information about cell signaling that supports the claim?

Group of answer choices

The SRY gene produces a protein that binds to specific regions of in certain tissues, which affects the development of these tissues.

The SRY gene produces a protein that deletes portions of the X chromosome in males so that male characteristics can develop.

The SRY gene produces and RNA segment that is exported from specific cells and targets the developing gonads

The SRY gene is found only in tissues of the developing gonads.

ANSWER: MITRAL VALVE STENOSIS

EXPLANATION:

The child have the risk of having MITRAL VALVE STENOSIS. It is also referred to as mitral stenosis.

Mitral valve stenosis occurs as results of the mitral valve opening narrowing. Which effect to less blood flowing through it.

The mitral valve is located between two chambers (the atrium and the ventricle) on the left side of your heart.

However, Mitral valve stenosis can lead to different health issues, including blood clots, difficulty breathing, fatigue, and heart failure.

Mitral valve stenosis is specifically caused by rheumatic fever (a childhood disease). This rheumatic fever occurs has a result of the body's immune response to an infection associated with the streptococcal bacteria.

Acute rheumatic fever affects the joints and the heart greatly. It causes joints inflammation temporarily and in severe case causes chronic disability.

Nevertheless, this cardiac complication have treatment and it is based on whether the affected individuals shows symptoms. Medications like blood thinners or anticoagulants (to reduce the risk of blood clots), diuretics, antiarrhythmics (to cure abnormal heart rhythms), beta-blockers (to slow your heart) etc, are being administered based on the level of the complication.

1. What characteristics do the mountains in a mountain range have in common?
lesantik [10]

Answer:

Mountains are prominent landforms that have significant heights above sea level and/or the surrounding land. They are steeper than hills. A mountain or mountain range usually has a peak, which is a pointed top. Mountains have different climates than land at sea level and nearby flat land. Climate is the weather over an extended time period for a specific area. The climate of mountains tends to include colder weather, wetter weather, and thinner air. Thin air refers to the fact that at the higher altitudes of a mountain there is less oxygen to breathe. Also, mountains generally have less hospitable conditions for plants and animals. This leads to quite different evolutionary adaptations for those plants and animals that make higher elevations their home.

The meselson-stahl experiment supported which mechanism for dna replication? see section 15.2 (page 320) .
Arte-miy333 [17]
Answer;
DNA replication is semi-conservative.
The meselson-stahl experiment supported the hypothesis that DNA replication is semi-conservative.

Explanation;
The Meselson-Stahl experiment
was an experiment by Meselson and Stahl that proved that the semi-conservative model by Watson and Crick was correct. 
DNA replication is semi-conservative in the sense that the new helices formed after replication contain, one new DNA strand and one old strand from the parent DNA molecule.

Suggest how a dimetrodon would have to behave in order to use its sail to warm its body
Alecsey [184]

Answer:

Dimetrodon (/daɪˈmiːtrədɒn/ (About this soundlisten)[1] or /daɪˈmɛtrədɒn/,[2] meaning "two measures of teeth") is an extinct genus of non-mammalian synapsid that lived during the Cisuralian (Early Permian), around 295–272 million years ago (Ma).[3][4][5] It is a member of the family Sphenacodontidae. The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first erected in 1878.

Explanation:

Dimetrodon is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it became extinct some 40 million years before the first appearance of dinosaurs. Reptile-like in appearance and physiology, Dimetrodon is nevertheless more closely related to mammals than to modern reptiles, though it is not a direct ancestor of mammals.[4] Dimetrodon is assigned to the "non-mammalian synapsids", a group traditionally called "mammal-like reptiles".[4] This groups Dimetrodon together with mammals in a clade (evolutionary group) called Synapsida, while placing dinosaurs, reptiles and birds in a separate clade, Sauropsida. Single openings in the skull behind each eye, known as temporal fenestrae, and other skull features distinguish Dimetrodon and mammals from most of the earliest sauropsids.
