Answer:

Tropical dry Climate: The weather is sunny pretty much all year. The ocean + the sun allows a tropical place to be great for growing food. Things such as coconuts and mangoes can be found. Its a great place to vacate because of the sunny climate, also clients will fall in LOVE with the warm beaches. Some activities would be to surf, sunbathe, and study the natrual habitat. The animals are also very interesting. Monkeys and chameleons would be great temporary pets to take care of.

I hope this was good enough, god bless you!!

In Drosophila, vestigial (partially formed) wings (vg) are recessive to normal long wings (vg+) and the gene for this trait is a

Marina CMI [18]

Answer/ Explanation:

a. The genotype of a homozygous white eyed long winged female would be Vg+Vg+XrXr. We denote the white allele as recessive (r) because the XY male only has one copy and yet has red eyes, so the red eye trait (R) must be dominant. A homozygous red eyed vestigial winged male would have be VgVgXRY. The possible gametes for the female are Vg+Xr only. For the male, the possible gametes are VgXR or VgY

The attached punnett square shows the results of the cross. The females will all be Vg+VgXRXr. The males will all be Vg+VgXRY (must inherit Y from father). That means they will all have normal length wings, the males will have white eyes and the females will have red eyes.

b. The F2 flies arise from intercrossing the F1, so the cross will be Vg+VgXRXr x Vg+VgXRY. The possible gametes for the mother are: Vg+XR, Vg+Xr, VgXR or VgXr. The possible gametes for the father are Vg+Xr

, Vg+Y

, VgXr

, VgY

. The attached punnet square shows this cross. The ratio of the phenotypes will be 6:6:2:2, or 3:3:1:1 (long-winged red eye: long-winged white eye: vestigial wing red eye: vestigial wing white eye), genotypes shown in the attachment.

c. F1 cross back to the mother would be Vg+VgXRY x Vg+Vg+XrXr. The genotypes are shown in the attached punnet square. The offspring will all be long-winged with white eyes. The F1 to the father would be Vg+VgXRXr x VgVgXRY. The ratio would be 3:3:1:1 long-winged red eye: long-winged white eye: vestigial wing red eye: vestigial wing white eye

which classification level is broader than the kingdom level; which branch of biology is concerned with the naming and classifyi

shtirl [24]

Domain is broader than the kingdom level.

Levels of classification that are broader than phylum are regions and kingdoms. There are five kingdoms: Monrea, Protista, Fungi, Plants.

Taxanomy is the branch of biology concerned with the naming and classifying of organisms.

Protists are described as diverse organisms because they have many different characteristics. They are either heterotrophs or autotrophs. They are also eukaryotes that are not classified as plants, animals or fungi.

Animals group of organisms includes only multicellular heterotrophs.

If two species belong to the same class, they also belong to the same taxon higher up in the hierarchy. Here they belong to the same side and kingdom.

The gradual change in a species over time is called Evolution.

The levels of classification that are broader than the phylum are domains and kingdoms.

Taxonomy is the science of naming, describing and classifying all living organisms, including plants.

The stage of spinal shock that follows spinal cord injury is characterized by a. absent spinal reflexes below the level of injur

IrinaVladis [17]

Answer:

The correct answer is a. absent spinal reflexes below the level of injury.

Explanation:

Spinal shock strictly refers to the neurological condition that occurs immediately after a spinal cord injury, in which the loss of not only motor and sensory functions occurs, but also the abolition of all reflexes below the injury (reflexes of muscular or myotatic stretching and cutaneous reflexes). There is also flaccidity, loss of reflexes. It is characterized by hypotension associated with cervical or upper thoracic spinal injuries. This characteristic shock results from the lesion of the descending sympathetic pathway in the spinal cord, producing a loss of vasomotor tone and sympathetic innervation of the heart. This causes vasodilation of the affected area with accumulation of blood and a decrease in venous return to the heart as well as cardiac output.
