The head makes up the largest percentage of body size __12___ weeks after fertilization.
What is fetal development of head?Fetus brain development is a complex process that continues throughout the pregnancy. At just six weeks, the embryo’s brain and nervous system begin to develop, although the complex parts of the brain continue to grow and develop through the end of pregnancy, with development ending around the age of 25.
At 11 weeks of pregnancy, baby’s head is about half the length of his body. Gradually, the body lengthens out and by about 28 weeks of pregnancy, baby’s body and head look a whole lot closer to normal.
Thus, the best option is B, i.e, 11 weeks among the given alternatives for the question.

Your answer should describe the nature of the environmental impact and how the impact would affect the anatomy and physiology of photosynthesis of the plant.The environments are:A. Desert. Prairie
Answers
Answer:
Desert.
Explanation:
Photorespiration occurs in C3 plants because their photosynthetic activities are disturbed due to high temperature of the environmental while on the other hand, C4 plants has absent this photorespiration process. The desert environment has direct impact on the plants having photorespiration due to its high temperature of the surrounding as compared Prairie where the environment is moderate so the C3 plants has high chances of photorespiration in desert condition as compared to Prairie.
How do divisions in the geologic time scale differ from the way we organize time using a clock?
Answers
Explanation:
The Earth's geologic past is divided into hierarchical time periods. This hierarchy comprises eons, eras, times, epochs, and ages, from largest to smallest. The Cenozoic, Mesozoic, and Paleozoic Periods are the three main divisions of the Phanerozoic.
The geological timescale is the official earth clock and differs from the way we organize time using a clock, as the planet's time is too long for us to use measures of hours.
Geologic timescalePlanet Earth is about 4.5 billion years old. To better understand its history, scientists divide geologic time into five levels of classification, called chronostratigraphic units:
EonsErasPeriodsEpochsand ages.Eons are large and indeterminate spans of time and are divided into four classifications:
Phanerozoic (last 542 million years)ProterozoicArcheanand Hadean.Of them, only the Hadean is not divided into ages. The ages are characterized according to the different positions of continents, oceans and their living beings. Within the ages are divided in the periods. Epochs, in turn, are divisions within periods and are divided into ages. According to the researchers, we currently live in the Quaternary period of the Cenozoic era.
To get a rough idea of how much the existence of the human being is a mere recent episode in Earth's geological time, we use some analogies. For example, if the entire history of the planet were summarized in the twenty-four hours of a day, the existence of humanity would have occurred in the last three seconds of that same day.
Understanding the dimension of geological time and its scales of measurement becomes a fascinating mental exercise to better understand the role of man in relation to this temporality and his role as heir of all the transformations that have taken place in terrestrial space throughout the geological ages.

Increasing sea surface temperatures should...
Lower the amount of dissolved oxygen in the ocean, depriving many
invertebrate animals of oxygen necessary to live.
Lower the amount of sea ice in polar areas. This will warm the water,
decreasing the abundance of primary producers and the number of
organisms that eat these producers.
Increase the temperature difference between the upper and lower parts of
the ocean, making upwelling less likely to occur. This will decrease ocean
nutrient levels, affecting the number of primary producers.
Raise water temperatures above the tolerance limits for many aquatic
organisms in tropical areas, increasing stress on these species.

ranges overlap, the species do not mate with each
other. What most likely prevents these two species
from interbreeding?
A. habitat isolation
B. gametic isolation
C. geographic isolation
D. reproductive isolation
Answers
Reproductive isolation is a mechanism through which species do not get to interbreed. Option D. reproductive isolation
What is reproductive isolation?This is a mechanism through which different species or populations do get to mate and produce fertile offspring. This mechanism allows the accumulation of genetic differences and favors speciation.
There are different barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers prevent mating between two or more species. There are two types of barriers,
prezygotic ⇒ that avoids fertilization between individuals of different species, postzygotic ⇒ that impedes the zygote to develope and reach the adult stage.Pre-copulatory o pre-ziygotic:
• Ecological or by habitat isolation;
• Seasonal or temporal;
• Séxual o ethologic;
• Mechanic;
• Gametes incompatibility.
Postzygotic mechanisms or barriers include
• Hybrid inviability,
• Hybrid sterility,
• Cytoplasmic interactions.
In the exposed example occurs a seasonal difference between the mating period of the eastern spotted skunk and the western spotted skunk.
Probably, if both of them would mate during the same season and in the same area, they could reproduce.
However, since their mating season differs, individuals from each species do not get to cross and hence, produce fertile offspring.
Option D. reproductive isolation is what most likely prevents these two species from interbreeding

13-22 Aquaculturists (people who farm marine resources, typically in semi-enclosed areas off the coast) have development methods of growing various invertebrates as food sources, such as clams, mussels, and oysters. Other widely consumed species, such as squid, have never been successfully grown in controlled marine environments, and so they remain wild caught. Why
Answers
Answer: There are several problems associated with handling of the squid.
Explanation:
Squid is a deep sea creature which becomes enormously big in size and difficult in handling in artificial water body or aquaculture.
It consumes and requires huge amount of food in the pre-larval stages typically phytoplankton and it becomes difficult to provide such food to them.
The maintenance of temperature, and salinity for the squid in aquaculture is difficult.
The sticky arms of the squid adhere to the surface of tub or human handler making it difficult to handle and can be poisonous to humans too.
