Answer:

The greatest difference between high and low tide is around New Moon and Full Moon. During these Moon phases, the solar tide coincides with the lunar tide because the Sun and the Moon are aligned with Earth, and their gravitational forces combine to pull the ocean's water in the same direction.

mylen [45]

In the warm southwest United States rabbits are brown and have long ears. In Polar Regions rabbits are white and have shorter ears. But rabbits from Polar Regions have white fur. Because to protect from predators and mould to survive in cold environment.

<u>Explanation: </u>

Shortened ears and a thick, white coat are some of the physical features created by snow bunnies to survive in the hard, frozen tundra. The polar rabbits (hares) live in the cruel climate of the North American tundra.

These hares do not lie dormant, but survive a dangerous cold, adapting to various behavioural and physiological changes. They have thick coats and a low surface to volume ratio that accumulates body heat, which is most noticeable in their shortened ears.

Hares sometimes dig a shelter in the snow and crawl together to share the warmth. In winter, they have a beautiful white jacket that provides great camouflage on ice and snow.

Purple flowers are dominant over white flowers. A heterozygous purple flower is crossed with another heterozygous purple flower.

Anna007 [38]

You need to draw a punnet square:
_______
__|P | w |
|P |PP| Pw|
|w |Pw| ww|

So that means you'll have:
1/4 PP flowers, which are homozygous purple flowers
2/4 Pw flowers, which are heterozygous purple flowers
1/4 ww flowers, which are homozygous white flowers

So the ratio of purple to white flowers is 3:1

The portion of the small intestine that attaches to the cecum is the? appendix. ileum. haustrum. jejunum. duodenum

Rus_ich [418]

The portion of the small intestine that attaches to the cecum is the Ileum.

Hence Option (b) is correct.

With a length of almost 1.8 m(6 feet), the ileum is the section of the small intestine that is the longest.

Compared to the jejunum, it is thicker, more vascular, and has more advanced mucosal folds.

At the ileocecal sphincter, the ileum connects with the cecum, the first segment of the large intestine (or valve).

The small intestine's coiled tube is separated into three sections. These are the duodenum, jejunum, and ileum, arranged proximally (at the stomach) to distally.

The 25.4 cm (10 in) long duodenum, which starts at the pyloric sphincter, is the shortest section.

The jejunum connects the duodenum to the ileum and is roughly 0.9 m (3 feet) long (in life). The jejunum and the ileum, the last section of the small intestine, do not have a distinct boundary.

Hence, The portion of the small intestine that attaches to the cecum is the Ileum.
