Answer:
The shape of the thigh bones confirms Orrorin was bipedal. The earliest hominid with the most extensive evidence for bipedalism is the 4.4-million-year-old Ardipithecus ramidus.
Explanation:
Major morphological features diagnostic (i.e., informative) of bipedalism include: the presence of a bicondylar angle, or valgus knee; a more inferiorly placed foramen magnum; the presence of a reduced or nonopposable big toe; a higher arch on the foot; a more posterior orientation of the anterior portion of the iliac
Early hominid fossils were examined and scientists concluded these hominids exhibited bipedalism. This confirms that they belong to Orrorin.
The shape of the thigh bones of the hominid fossil confirms that it belongs to Orrorin species which was bipedal. The earliest of the hominid fossils with the most extensive evidence for bipedalism is almost about 4.4 million year old Ardipithecus ramidus.
Major morphological features which are diagnostic or informative of bipedalism in the species include the presence of a bicondylar angle, or the valgus knee. It is a more inferiorly placed foramen magnum and is the presence of a reduced or the non-opposable big toes. A higher than normal arch on the foot and a more posterior orientation of the anterior portion of the iliac

2. How do the parts of the circulatory system work together
Answer:
The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.

Farmers can trigger uniform ripening times in fruit by treating plants with ________. Ethylene ethylene oligosaccharins oligosaccharins jasmonates
Answer:
ethylene is the blank word
Explanation:
Farmers can trigger uniform ripening times in fruit by treating plants with 2. ethylene.
Ethylene is a plant hormone that plays a crucial role in the ripening process of fruits. It is a gaseous hormone that acts as a signaling molecule, influencing various physiological processes in plants, including fruit ripening.
When plants produce ethylene naturally, it acts as a signal to initiate and coordinate the ripening of fruits. Ethylene triggers a cascade of biochemical and physiological changes that lead to fruit softening, color development, flavor enhancement, and aroma production.
Farmers can exploit the role of ethylene in fruit ripening by treating plants with exogenous ethylene. By applying ethylene to fruit crops, farmers can induce uniform ripening times, ensuring that the fruits in a crop reach the desired stage of ripe-ness simultaneously.
This technique is particularly useful for commercial fruit production, where uniform ripening is desirable for efficient harvesting, storage, transportation, and marketing purposes. It allows farmers to coordinate the timing of fruit ripening, leading to more consistent quality and appearance across the crop.
It's worth noting that other methods can also be used to manipulate fruit ripening, such as the use of synthetic plant growth regulators or other hormones. However, ethylene is one of the primary hormones involved in the natural ripening process, and its exogenous application is a commonly used method to trigger uniform ripening times in fruit crops.

Spectrophotometry is a method to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution. The basic principle is that e ach compound absorbs or transmits light over a certain range of wavelength.
The amount of light absorbed in spectroscopy is defined by measuring the intensity of light when a beam of a particular wavelength passes the sample solution.
What is Spectroscopy?Spectroscopy may be defined as a type of technique that measures how much light is absorbed by any solution at a specific wavelength.
Spectroscopy is mainly used for investigating the structure and configuration of atoms and molecules. It is also used in finding the unknown chemical composition of materials in any solution.

Answer:
The answer is C. trapped greenhouse gasses
Explanation:
The greenhouse effect is the warming of the Earth's surface and troposphere (the lowest layer of the atmosphere) produced by the presence of water vapour, carbon dioxide, methane, and other gases in the atmosphere. Water vapour has the greatest impact of the gases classified as greenhouse gases.

What are the advantages and disadvantages of reproducing by spores.
Explanation:
These spores can be produced quickly and in large numbers to enable many individual fungi to develop. A disadvantage of these spores is that they generate offspring that are unlikely to be resistant to unfavourable conditions because they are all genetically identical.
Advantages The organism does not need male and female reproductive organs.Organisms do not waste their energy unnecessarily in producing male and female gametes.Large numbers of spores are produced in one sporangium.Spores do not require any medium for dispersal. They are rounded and very light in weight and hence can be easily transferred for germination.Spores are distributed easily by air to far-off places to avoid competition at one place.Spores are covered with thick walls to prevent dehydration under unfavourable conditions.Disadvantages :A disadvantage is that the spores will be clones of the original organism, leaving them vulnerable. Spore reproduction is quick and multiplies many at once, hence the population will increase and survival chances are high. They remain dormant till favourable conditions are available. As they are light, they can be carried by wind and hence can start growing in different regionsWhat is happening to the DNA molecule in the figure?(Explain the first step in DNA replication)

Answer:

Explanation:
Like dogs, bears lose some of their soft, dense insulating underfur as well as some of their coarse outer guard hairs when temperatures climb. That’s why bears can look very scruffy by late summer. As the weather cools and they layer on fat for hibernation, their underfur and guard hairs grow back.
