Trava [24]2 years ago
7 0

Answer:

absorb water from the soil by osmosis.

Explanation:

Root hair cells

Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption

Cattle - brucellosis pretend you are an epidemiologist, and recommend a comprehensive disease-control program for keeping the he
Oksanka [162]

Worldwide, brucellosis is a disease that must be reported in the majority of nations.

The illness manifests as flu-like symptoms such as fever, malaise, weakness, and weight loss.

Transmission from person to person is uncommon

Brucella species, which primarily infect cattle, swine, goats, sheep, and dogs, are responsible for the bacterial disease known as brucellosis.

A number of Brucella species, which primarily affect cattle, swine, goats, sheep, and dogs, are responsible for the bacterial disease brucellosis. Humans typically contract the illness through close contact with infected animals, consumption of tainted animal products, or inhalation of airborne agents. Consuming unpasteurized milk or cheese from infected goats or sheep is the primary cause of the majority of cases.

>Steer clear of unpasteurized dairy products. Few brucellosis cases have recently been linked to raw dairy products from domestic herds in the United States.

>Cook meat completely.

>Put on gloves.

>In high-risk workplaces, practice safety precautions.

>Vaccinate household pets

>Doxycycline and rifampin are typically administered together for 6–8 weeks.

>To stop the disease from coming back, you must take the antibiotics for a number of weeks.

> Relapse rates after treatment range from 5 to 15%, and they typically happen within the first six months.

Operons are a(n) ____ sequence lying adjacent to the DNA being transcribed and are composed of a promoter located next to a(n) _
sladkih [1.3K]

Answer:

d. regulatory; operator; regulatory  

Explanation:

In prokaryotes, the regulation of gene expression is done at the transcription level by operons. Examples are the lac operon and the trp operon.  To initiate transcription, RNA polymerase and a DNA segment are required for binding called a promoter.

DNA segments that are close to the promoter serve as binding sites for regulatory, activating or repressing proteins. They are called operons.

The Operon is a regulatory sequence close to prokaryotic DNA that lies between the structural genes and the promoter. It is responsible for controlling the transcription of structural genes. When the repressor, encoded by the regulatory gene, binds to the operator, the promoter is blocked which prevents transcription.

The Promoter is located next to an operator and is the site in the DNA molecule that binds to RNA polymerase (which is a regulatory protein) to initiate transcription.

What is the “transitional fish”
tester [92]

Answer:

375 million-year-old fish, a large scaly creature not seen before, that they say is a long-sought "missing link" in the evolution of some fishes from water to a life walking on four limbs on land. In addition to confirming elements of a major transition in evolution, the fossils are widely seen by scientists as a powerful rebuttal to religious

Explanation:

on closer examination, scientists found telling anatomical traits of a transitional creature, a fish that is still a fish but exhibiting changes that anticipate the emergence of land animals — a predecessor thus of amphibians, reptiles and dinosaurs, mammals and eventually humans
