Answer:
The correct answer is B. clavicle articulates with the manubrium of the sternum.
Explanation:
The clavicle is an anterior bone whose sternal end articulates with the manubrium of the sternum at the sternoclavicular joint. The sternal end is also anchored to the first rib by the costoclavicular ligament. The medial end, also known as the sternal end of the clavicle, has a triangular shape and articulates with the manubrium portion of the sternum. This forms the sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton.
<h2>Savanna & tropical rainforest</h2>
Explanation:
- Savanna is a grassland biome which is found South America .it is a type of natural biome which is changes during seasonal pattern for examples- elephants,cheetahs, wildebeest
- It is here and there found in mild atmospheres, for the most part in zones that are transitional zones among grassland and forests.
- Tropical rainforests are forests in the tropics that get more than 100 crawls of precipitation every year.
- This unbelievable species extravagance is expected to a great extent to the blend of a tropical atmosphere and high, all year precipitation, which gives ideal developing conditions to the biggest number of plant species.
- The warm, wet conditions in the tropical rainforest cause quick disintegration of any waste, and on the grounds that daylight and water are abundant, any supplements discharged into the dirt are quickly utilized by the quickly developing vegetation, leaving the dirt incredibly poor thinking about the high efficiency of the biome as long as the backwoods stays flawless, supplements will rapidly burn through the environment.

Answer:
The correct answer is D: diploid phase
Explanation:
The essence of plant life is their characteristic property of alternation of generations. Each plant undergoes alternation of generations and produces haploid and diploid generations.
This property allows the plant to reproduce both sexually and asexually. Primitive plant species used to reproduce through spores and spent the majority of their life as haploid cells. These cells were called as spores and required only matter and energy to reproduce.
Modern plant species reproduce by using gametes and spent the majority of their life in diploid phase called diploid sporophytes.
Answer: if i want to breed a rose and i don't have a certain kind of rose, i have to cross between them until i have a kind of rose that express the phenotype i was looking for. Once i've got it, i'll try to cross it with another rose and generate more species like that to cross with the rose that express the phenotype, this favors to generate a specie that have a pure phenotype.
Explanation: The answer is explain by the Mendel's laws.
Mendel's second law:
if you have two roses that are heterozygous and you cross them, their offspring have a 25% probability of generating a homozygous phenotype for a certain recessive characteristic (such as the rich smell of roses that is not a dominant character), 50% of generate heterozygotes with a dominant phenotype, and 25% generate other homozygotes with a dominant phenotype.
Once the offspring with the recessive homozygous character are obtained, it is possible to start making crosses between those of a recessive nature and there Mendel's first law applies
All the homozygous recessive individuals that are crossed will have a 100% homozygous recessive offspring.
Also, if you cross heterozygotes with another heterozygotes the offspring will be 100% heterozygotes
