The correct answer is B. Meet current and future resource needs.
Explanation:
Sustainability implies an equilibrium between the natural resources available and the resources humanity requires. This equilibrium is reached when the natural resources extracted from nature are enough to satisfy human needs without depleting the resources or causing these are not available in the future. In this context, the goal of sustainable development is to make sure now and in the future resource needs are meet (option B). Moreover, this is possible through actions such as recycling, reducing deforestation, creating environment-friendly technologies, among others that reduce the depletion of resources or preserve the environment.
Identical and obviously duplicated gene sequences have gotten from one chromosome to another by chromosomal translocation.
In terms of genetics, a translocation takes place when chromosome fragments and the (often two) fragmented portions reassociate with other chromosomes. For the diagnosis of several genetic diseases and syndromes, the finding of chromosomal translocations can be crucial.
Multigene families are groups of related or identical genes that have developed by gene duplication. It is thought that a single ancestral gene was duplicated and varied to create multigene families. The multigene families that code for actins, hemoglobins, immunoglobulins, tubulins, interferons, histones, etc. are a few examples.

Nuh uh! pls- i would like u to take some time and think about how the person that’s behind the screen’s feeling. why would u want us to answer your whole ASSIGNMENT?! make it make sense!!! ❤️
Hello There!!
<span>The blood is the circulating fluid connective tissue. It is the system of blood, heart and blood vessels. The main function of this system is to distribute the digested food and oxygen to the different parts of the body, in order to release energy to carry out life activities.

1. Heart · Heart is triangular muscular pumping organs. · Heart of frog is situated ventrally to the liver in the pericardial cavity. · Heart is three –chambered. · Upper two chambers are called auricle sand lower one chamber is called ventricle. · Its anterior end is broader then posterior end. · The broader part anterior is known as auricle. · The posterior part is known as ventricle. · The ventricle is thick walled than auricles .right auricle is larger than left auricle.
Arterial system of frog
Blood vessels, which carry oxygenated blood away from heart to different part of the body, are called arteries. They constitute a system called arterial system. Truncus arterious gives two branches right aortic trunk and left aortic trunk. Each aortic trunk again divides into three branches- a) Carotid arch: it divides into – Lingual artery – it supplies blood to tongue and hyoid. Common carotid – it supplies blood to buccal cavity and brain. it consists swelling at the base called carotid labyrinth.
b) Systemic arch – two systemic arches move upward and then curve backward to join each other behind the heart to form dorsal aorta before meeting each other each systemic arch gives- Oesophageal artery – it supplies blood to osephagus. Occipito vertebral artery – it supplies blood to head and vertebral column. Subclavian – it supplied blood to shoulder and forelimb. From the junction of two systemic arches coeliaco – mesenteric artery arise which gives following branches. Coeliac artery arises and gives two branches – Hepatic artery artery – it supplies blood to liver. Duodenal artery –it supplies blood to duodenum. Intestinal artery – it supplies blood to small intestine (ileum). Spleenic artery – it supplies blood to spleen (meeting place of ileum and rectum). Posterior mesenteric artery- It is Long Branch and supplies blood to the rectum. The dorsal aorta runs backward and gives following branches- Gonadial artery – it supplies blood to testes and ovary. Renal artery- it supplies blood to kidney. At the end, the dorsal aorta runs posterior and bifurcates into right and left common iliac arteries. Each of iliac arteries gives Femoral artery – it supplies blood to hip and thigh. Sciatic artery – it supplies blood to lower region of hind legs. Epigastric artery- it supplies blood to urinary bladder.
c) Pulmo-cutanous arch- it divides into Pulmonary artery – it receives deoxygenated blood from different parts of the body and open into lungs. Cutanous artery- it supplies oxygenated blood to skin.
Venous System of frog
Blood vessels, which carry the deoxygenated blood from different parts of the body to the heart, are called veins. They constitute a system called venous system. Venous system of frog can be studied under too heading
A) Systemic Venous System This system includes the three large veins, which receives the deoxygenated blood from all the parts of the body and collect to the sinus venous. The three veins are- Right Precaval, Left precaval and Post cavals
1. Right and Left Precaval Vein: Each precaval is formed by the union of 3 veins External jugular vein - it is formed by the two veins. a. lingual vein – it receives deoxygenated blood from mouth and tounge. b. mandibular vein – it receives deoxygenated blood from lower jaw. innominate vein – it is formed by two veins. a. internal jugular vein- it receives deoxygenated blood from eye brain and skull. b. subscapular vein- it receives deoxygenated blood from shoulder and arm.subclavian vein- it is formed by two veins- a. brachial veins- it receives deoxygenated blood from fore limb. b. muscub cutanous vein – it receives deoxygenated blood from muscles and skin.
2. Post Caval Vein: It receives deoxygenated blood from following 3 veins. Hepatic vein- it receives deoxygenated blood from liver. Gonodial vein- it receives deoxygenated blood from gonads. Renal vein – it receives deoxygenated blood from kidney.
B) Pulmonary Venous System The pulmonary vein receives pure blood from lungs into left auricle of heart
